Spray & Hose Assemblies

Spray and Hose Assembly Products

Products in this category fall into six functional groups, based on how the spray connects and where the hose installs.

Side Spray and Hose Assemblies

A side spray mounts in a separate deck hole beside the faucet. The kitchen sink sprayer hose runs below the deck and connects to the diverter outlet on the faucet body. Side spray hoses are commonly 3/8 in. by 48 in. The hose usually attaches at the outlet with a threaded or quick-connect fitting.

Pull-Down Spray and Hose Assemblies

A pull-down faucet hose assembly feeds a spray wand that docks in a high-arc spout and pulls straight down into the basin. A hose weight under the sink returns the wand after use.

Pull-Out Spray and Hose Assemblies

A pull-out faucet hose assembly serves a lower-profile spout with a wand that extends forward. The hose relies on a weight or guide to retract without binding.

Replacement Hose Kits

Kitchen faucet hose kits replace a damaged hose while keeping the existing spray head. Kits may include the hose, a weight, and adapters. kitchen faucet replacement hoses are sized to the original fittings and length.

Replacement Spray Heads

Spray heads attach to the end of the kitchen faucet spray head hose and control the spray pattern, often with a stream and spray toggle. Replace the head when the trigger sticks, the face clogs with mineral buildup, or the internal seal leaks. Match the head's finish to the faucet.

Hose Guides, Weights, and Connectors

Guides, weights, and connectors keep the hose routed correctly under the sink. Guides stop the hose from catching on valves, weights retract the wand, and connectors join the hose to the outlet or supply. Missing guides are a common cause of hose wear.

How Spray and Hose Assemblies Work and Where to Use Them

How Side Spray Systems Divert Water

In a side spray faucet, water flows to the spout until the sprayer trigger is pressed. The pressure drop shifts a diverter valve in the faucet body, which channels flow to the kitchen faucet spray hose. A worn diverter, kinked hose, or clogged head can weaken the spray, though aerators and cartridges can also restrict flow.

How Pull-Down and Pull-Out Hoses Retract

Integrated wands retract by gravity. A weight clamped to the hose below the deck pulls the hose back through the spout. Some faucets also use a docking magnet in the spray head to hold the wand in place. If the wand stops short of docking, check that the weight sits at the marked position and that the hose is not snagging on supply lines, drain parts, or stored items.

Where These Assemblies Install

These parts install on residential kitchen sinks, bar and prep sinks, break-room and office kitchens, and multifamily units during turnover. Service technicians use them for leak repairs, and remodel contractors replace worn assemblies when the faucet body itself is still serviceable and does not need replacement.

Key Specifications and Planning Steps

Connections and Thread Size

Hoses connect through threaded fittings or quick-connect ends that push on and release with a clip or button. Thread sizes vary by manufacturer, so match the existing fitting or the faucet part number. Inspect O-rings and washers at each end, and replace them with the hose.

Hose Length and Diameter

Side spray hoses are often near 48 in. long, while pull-down and pull-out hoses are commonly about 59 in. Measure the existing hose first and allow slack for the weight.

Materials and Drinking-Water Compliance

Common hose jackets include braided nylon, braided stainless steel, and vinyl. Wetted parts must meet the federal 0.25 percent weighted average lead limit. Confirm through NSF/ANSI 372 certification or manufacturer documentation.

Replacement Planning Steps

 1. Record the faucet model.

 2. Shut off both supply valves.

 3. Disconnect the hose at each end.

 4. Compare ends and length to the new part from faucet parts and repair.

 5. Install, set the weight, and test for leaks.

Choosing the Right Spray and Hose Assembly

Start with the faucet itself. For commercial and multifamily work, stocking the same assembly for repeat faucet models shortens future service calls. The brand and model number determine whether a universal kitchen faucet spray assembly will fit or whether a manufacturer-matched part is required. Integrated pull-down and pull-out wands usually need a matched hose, while many side sprays accept universal parts. Next, confirm that the connection type, hose length, and finish match the existing faucet and any faucet trims on the sink. When the faucet body is corroded or the cartridge has also failed, a new faucet from kitchen and bar faucets may take less labor than servicing spray and hose assemblies separately.

Frequently Asked Questions

Where can plumbing contractors buy spray and hose assemblies for kitchen faucets?

Plumbing supply distributors and faucet manufacturer parts programs stock spray and hose assemblies. Order by the faucet brand and model number, or by the part number on the old hose or in the faucet documentation, to confirm fit before the service call.

What should be checked before ordering a kitchen faucet hose replacement?

Before ordering a kitchen faucet hose replacement, confirm the faucet brand and model, the faucet type (side spray, pull-down, or pull-out), the connection style at each hose end, the required hose length, and the spray head finish if a head is included.

What is the difference between a pull-down and a pull-out faucet hose assembly?

A pull-down faucet hose assembly serves a high-arc spout, and the wand pulls straight down into the basin. A pull-out faucet hose assembly serves a lower spout, and the wand extends forward. Both run through the faucet body and use a weight or guide to retract.

Does a kitchen faucet need a side spray hose or a pull-out spray hose?

It depends on the faucet design. A faucet with a separate sprayer in its own deck hole uses a side spray hose connected to a diverter outlet. A faucet with a wand built into the spout uses an integrated pull-down or pull-out hose. The two are not interchangeable.

Which kitchen faucet spray hose materials hold up to frequent daily use?

Hoses with a braided jacket, such as braided nylon or braided stainless steel, generally resist abrasion and kinking more than plain vinyl. Durability also depends on the inner liner and fittings, so check the manufacturer's specifications for the kitchen faucet spray hose being considered.

Why is a kitchen sink sprayer hose leaking under the sink?

A leaking kitchen sink sprayer hose usually points to a worn inner liner, a cracked hose, a loose connection at the faucet outlet, or a failed O-ring or washer at the spray head. Reseat or tighten the connection first, and replace the hose if the jacket or liner is damaged.

 Why does a pull-down spray head not retract all the way?

Incomplete retraction is often caused by a hose weight that has slipped out of position, a hose snagging on supply lines or drain parts, or a missing hose guide. Reset the weight to the manufacturer's marked position and clear the hose path under the sink.

How do you fix low water pressure from a kitchen faucet side sprayer?

Check the spray head for mineral buildup, inspect the hose for kinks, and test the diverter valve, which can wear and restrict flow to the sprayer. Low flow can also come from partly closed supply valves, a clogged aerator, or a worn cartridge, so check those if the sprayer parts test clear.

How do you replace a kitchen faucet spray hose that uses a quick-connect fitting?

Shut off both supply valves, press the release clip or button on the fitting, and pull the hose free. Push the new hose in until it clicks, tug to confirm it is locked, reset the hose weight, and test for leaks. Threaded hoses follow the same steps with a wrench at each connection.

What causes a kitchen faucet spray hose to kink or crack, and when should it be replaced?

Kinks and cracks usually come from repeated bending at a tight point, contact with valves or stored items under the sink, and liner wear over time. Replace the hose when the jacket cracks, the hose stays kinked, or water seeps from the hose body rather than a fitting.

What size hose does a kitchen sink sprayer use?

Side sprayer hoses are commonly 3/8 in. in diameter and about 48 in. long. End fitting thread sizes vary by manufacturer, so match the replacement to the existing fittings or the faucet part number rather than diameter alone.

Are kitchen faucet replacement hoses universal?

Some are. Many side spray hoses use universal fittings, but most kitchen faucet replacement hoses for pull-down and pull-out faucets are built for a specific brand and model, because the connections at the spray head and faucet outlet differ. Check the faucet model before ordering.

How long should a replacement hose be for a pull-out kitchen faucet?

Pull-out and pull-down hoses are commonly about 59 in. long. The replacement should match the original length so the wand reaches the full basin and the hose weight has room to retract it. Measure the old hose or check the faucet part number.

Can you replace just the hose on a kitchen faucet, or do you need a full spray and hose assembly?

If the spray head works and seals correctly, kitchen faucet hose kits replace only the hose and keep the existing head. If the head leaks, sticks, or is clogged, a complete kitchen faucet hose assembly replaces both parts in one repair.

How can you confirm a kitchen faucet spray hose kit meets drinking-water requirements?

Federal law limits lead in the wetted surfaces of drinking-water fixtures to a 0.25 percent weighted average. Confirm compliance through the manufacturer's listed certification, such as NSF/ANSI 372, or through its product documentation and packaging markings.
