The Fire King QR40 is a quad-ring replacement seal for fire extinguisher valve assemblies. Unlike a standard round-cross-section O-ring, a quad-ring's four-lobed profile resists rolling and twisting in its groove, giving a more stable static seal at the valve stem after repeated servicing.
Key Features
- Four-lobed quad-ring profile resists twisting compared to a round O-ring
- Used to reseal the valve stem during recharge or valve service
Technical Specifications
- Seal profile: Quad-ring (X-ring)
- Application: Fire extinguisher valve stem
