Action Pump Rubber Ring ID21xOD30 Height 5mm Red Unifiber UF097060004

Description:

This precision replacement rubber ring is designed to restore and maintain airtight seals in Action-style hand and foot pumps used for SUPs, inflatables, kites and small boats. Molded from high-grade nitrile rubber for reliable elasticity and resistance to compression set, the ring retains sealing performance over repeated pump cycles. Its exact ID 21 mm / OD 30 mm / height 5 mm dimensions ensure a snug fit in compatible valve housings and piston assemblies, reducing air loss and improving pump efficiency. The bright red color makes identification and servicing quick and simple when performing maintenance or building a parts kit. Durable construction resists aging, ozone and common waterborne chemicals so it delivers long service life even in marine environments. Easy to install, the ring helps returns a worn pump to near-original performance and reduces the need for full pump replacement.

• High-grade nitrile rubber (NBR) construction for durability and elasticity
• Precision dimensions (ID 21 × OD 30 × H 5 mm) for reliable, leak-free sealing
