Have a leak at the connection between the QC Coupler and QC Plug or just want some spares?  

These O-Rings will fit in any standard QC Coupler.

• 1/4" fitting size is typically used for the spray gun outlet and lance fittings.
• 3/8" fitting size is typically used for connections on the power washer, hose and spray gun inlet.

The O-Ring material is FKM (Fluro-Elastomer) which is a durable compound that performs well with hot or cold water and is suitable for most chemical applications. Use the FKM Series of O-Rings for replacement on Stainless Steel Fittings.
