The Multiquip HS52010057 Fuel Cap with O-Ring is a genuine OEM replacement designed for the HS81 high-speed cut-off saw. This cap ships with the O-ring included, ensuring a complete, sealed installation right out of the box. As a direct OEM component, it meets the exact material and dimensional specifications of the original part. If you're servicing an HS81 and need a dependable fuel system seal, this is the correct replacement.
Key Features
- Integrated O-Ring Seal: — Ships with the O-ring already included, so the full sealing assembly is replaced in one step — no sourcing separate hardware.
- OEM Fuel Containment Spec: — Manufactured to the exact thread pitch, cap depth, and material grade of the original, ensuring a fuel-tight closure under operating conditions.
- Direct Fit for HS81: — Confirmed fitment for the Multiquip HS81 high-speed cut-off saw series; installs directly onto the original fuel tank neck with no modification.
- Prevents Fuel Leaks and Vapor Loss: — A worn or cracked fuel cap allows fuel vapors to escape and creates a leak risk during transport and operation; this replacement restores the proper sealed closure.
- Fuel System Safety: — A properly sealing fuel cap is a first line of defense against unintended fuel release near cutting sparks and hot surfaces — replacing a damaged cap promptly is a basic but critical safety measure.
The fuel cap seals the fuel tank opening on your cut-off saw, preventing fuel from spilling during transport and stopping vapors from escaping while the machine is running or stored. The integrated O-ring is what creates the airtight compression seal between the cap and the tank neck — when the O-ring degrades or the cap cracks, fuel can seep out and the tank may fail to hold pressure correctly. Replacing both the cap and the O-ring together with the Multiquip HS52010057 restores the full sealing function in a single service step.
