Captain O-Ring Power Pressure Washer O-Rings for 3/8" Quick Coupler

Upgrade your pressure washing setup with Captain O-Ring’s Power Pressure Washer O-Rings. This 10-pack uses Viton FKM rubber, a material known for chemical resistance and durability, designed to seal reliably where high-pressure cleaning meets tough cleaners. The O-Rings are sized to fit standard 3/8" quick-connect fittings, featuring a 1/2" inside diameter and a 0.100" thickness to help maintain a solid seal on many wands and hoses.

Key features

  • Viton FKM rubber delivers strong chemical compatibility with a wide range of cleaners and solvents used in outdoor cleaning.
  • Each O-Ring is 1/2" inside diameter x 0.100" thick, designed for 3/8" quick-connect fittings found on many pressure washer wands and hoses.
  • Tear and abrasion resistant construction helps maintain a tight seal through repeated connections and disconnects.
  • Temperature tolerance up to 400°F supports hot-water cleaning scenarios and demanding tasks.
  • Pack of 10 O-Rings, manufactured and warrantied by Captain O-Ring LLC.

Why these O-Rings can help your setup

Paraphrasing the data, these O-Rings are built to stay sealed under pressure, resist common cleaners, and stand up to heat. While results will depend on your equipment and usage, you may notice fewer leaks and easier maintenance when swapping seals between different cleaners or temperature settings. The Viton material adds resilience, which can contribute to longer-lasting seals in frequent-use environments.

Real-world use cases

  • Sealing connections on driveways, patios, and siding during high-pressure cleaning with detergents.
  • Maintaining leak-free seals on spray wands and hoses through repeated assembly and disassembly.
  • Using with hot water or heated detergents to maximize cleaning power without compromising seal integrity.

What’s included

  • Ten 1/2" ID x 0.100" thick Viton FKM O-Rings.
  • Manufactured and warrantied by Captain O-Ring LLC.
