PAGOW 40 Pack O-Rings for 3/8-Inch Quick Connect – Replacement Kit for Pressure Washers, Faucets & Hoses

Meet PAGOW's 40-pack O-rings designed for 3/8-inch quick-connect couplers. These small rings are the unsung heroes of a tight seal on pressure washers, faucets, and hoses. Crafted from abrasion-resistant NBR rubber, they stand up to everyday use and temperature changes, helping you maintain steady connections whether you are cleaning patios or watering the garden.

Each O-ring is sized for a precise fit: outer diameter around 17.1 mm (0.67 in) and inner diameter around 11.8 mm (0.46 in). The kit is built to be compatible with many connectors and cleaners, making it a versatile replacement option when a seal wears down or begins to leak.
