Faucet Gaskets (71 items found)

A small gasket can make a big difference. These simple seals sit between two surfaces inside your faucets and fixtures to create a watertight connection and prevent drips. Whether you're tackling a leaky kitchen faucet, fixing a bathroom sink or replacing a worn seal in a shower valve, the right gasket helps you get the job done quickly and correctly. Ace Hardware carries a wide selection of gaskets and plumbing essentials so you can handle faucet and faucet repair projects with confidence.

Common Gasket Types for Faucets and Fixtures

Not every seal is the same. Here are the most common types you'll find for household plumbing repairs:

• Flat gaskets:Placed beneath faucet bases, aerators and drain assemblies to create a flush seal between mating surfaces.
• O-rings:Round, flexible O-rings used inside faucet stems, cartridges and spouts to prevent leaks around handles.
• Cap-thread gaskets:Designed to seal threaded connections on valve bodies, cap-thread gaskets are available in rubber, nylon and fiber.
• Slip-joint gaskets:Also referred to as washers, slip joint gaskets are used in sink drain and trap connections where pipes slide together.

Gasket Materials and When to Use Them

Choosing the right material ensures a long-lasting, leak-free seal. Here's a quick breakdown:

• Synthetic rubber (including EPDM):Flexible, durable and water-resistant, a reliable choice for O-rings, flat gaskets and many general plumbing repairs.
• Nylon:Tough and reusable with strong resistance to wear. Works well for cap-thread gaskets and threaded valve connections that may need to be removed and reinstalled.
• Fiber:Lightweight and easy to compress for a snug fit. Commonly used in low-pressure connections like sink drains and supply line fittings.

How to Choose the Right Gasket

Selecting the correct gasket comes down to three things: size, material and where it's going. Here's how to narrow down the right fit:

• Measure the old gasket:Remove the worn seal and note its outer diameter, inner diameter and thickness. Bringing the old part to your local Ace makes it easier to find an exact match.
• Consider the fixture:A bathroom sink faucet may need a different gasket style or size than a tub and shower faucet.
• Check all connection points:If you're working on a kitchen faucet sprayer, inspect the hose connection for O-rings that may also need replacing.
• Match the material to the job:Use synthetic rubber for most water-line seals, nylon for threaded connections and fiber for low-pressure fittings.
• Grab the right tools:A basin wrench, pliers and adjustable wrench make gasket replacement easier. Browse plumbing tools to make sure you're ready before you start.
