Multipurpose 120-Pack Rubber Washer Kit

This 120-piece assortment supplies black rubber flat washers for household plumbing, garden hoses and general fastener sealing. Each washer has a 5 mm inner diameter, 11 mm outer diameter and 1.6 mm thickness. The synthetic rubber material resists deformation, corrosion and static buildup. Homeowners and maintenance crews can replace worn seals on faucets, shower hoses and watering tools with a single kit.

Sustained Sealing Performance

The synthetic rubber compound maintains high elasticity and air-tightness across temperature swings, so seals stay effective during prolonged exposure to water, oil or air pressure. Wear resistance and flame retardancy prevent the washers from hardening or cracking after repeated thermal cycles. This durability reduces the frequency of rework on outdoor irrigation systems and indoor fixtures alike.

Compatibility Check Before Ordering

Verify that the 5 mm inner diameter and 11 mm outer diameter match the fasteners or hose fittings you intend to seal. Confirm the 1.6 mm thickness provides the required compression allowance in your assembly. The kit contains only this single size; projects needing additional diameters will require a separate purchase.

Questions about this item

Do the 120 washers in this kit generate any heat or noise when used continuously in a plumbing system?

Rubber washers are passive sealing components; they produce no heat and make no noise during operation.

What tools or additional parts must I already have to install these 5 mm ID washers?

You need only basic hand tools such as an adjustable spanner or pliers to disconnect and reconnect the faucet or hose fittings.

Will these 1.6 mm thick washers seal properly on older faucet threads that may be worn?

The synthetic rubber material conforms to irregular surfaces, helping to seal minor thread wear on older fixtures.
