Stat-O-Seal Regulator Washers

Stat-O-Seal washers solve a small but critical problem in oxygen delivery: sealing the connection between a regulator and its gas cylinder so no oxygen escapes at the fitting. A worn or missing washer means a hissing leak, wasted gas, and an unreliable flow reading—which is why respiratory departments, EMS crews, and home oxygen users keep spares on hand.

This collection features the Allied Healthcare Stat-O-Seal Regulator Washer (86060-BR), a self-sealing washer built to fit standard CGA-870 yoke connections used on oxygen and medical gas regulators. Its bonded design combines a rubber sealing element with a metal washer body, forming a tight, leak-free seal each time the regulator is torqued onto the cylinder post.

Buyers typically ask three things. Do I need one? If your regulator connection leaks or the old washer looks cracked, flattened, or brittle, replace it—these are consumable parts meant to be swapped periodically. Will it fit? The 86060-BR matches the common yoke-style oxygen regulator inlet; confirm your regulator uses a CGA-870 pin-index post before ordering. How many should I stock? Because they're inexpensive and easy to lose during tank changes, most facilities order them in multiples so a fresh seal is always available.

Replacing the washer is simple: remove the old one from the regulator inlet, seat the new Stat-O-Seal squarely over the gas port, and hand-tighten the regulator onto the cylinder. A proper seal should hold pressure with no audible leak once flow is turned on.
