The BE Pressure 85.309.103C is a 100-pack of #112 EPDM O-rings sized for 3/8-inch quick-connect couplers on pressure washers. Power-washing contractors, fleet-wash crews, and rental-equipment shops buy them in bulk because a dried or missing coupler O-ring is the most common cause of a leaking, pressure-losing quick connect. Keeping a pack on the truck means a five-second fix instead of a lost job.
Use Cases
- Replacing worn O-rings on 3/8-inch quick-connect plugs and sockets that have started weeping or losing pressure.
- Bulk restocking for pressure-washing companies, equipment rental fleets, and repair shops that service many machines.
- Cold-water and general-purpose washing where EPDM's water and weather resistance outperforms standard rubber.
- Re-sealing brass or stainless quick-connect fittings after a hose, nozzle, or lance swap.

Frequently Asked Questions
What size O-ring is the 85.309.103C?
It is a standard #112 O-ring, the correct size for most 3/8-inch pressure washer quick-connect couplers and plugs.
Is EPDM good for hot water?
EPDM is rated for cold-water and general use. For sustained hot-water machines, BE offers the Viton version (85.309.103VC), which holds up better at high temperatures.
How often should coupler O-rings be replaced?
Replace them whenever you see weeping, pressure loss at the connection, or a flattened or cracked ring. With a 100-pack on hand you can swap proactively during routine maintenance.
Will these fit brass and stainless quick connects?
Yes. The #112 size seats in standard brass and stainless 3/8-inch quick-connect bodies.
