This is a genuine Craftsman replacement gasket, it is supplied directly from the original equipment manufacturer for use with air compressors. It is the special component which helps to provide an air-tight seal for the cylinder head assembly, over time the gasket may wear out and crack eventually requiring a replacement to maintain peak performance. This high-quality part is made of durable composite material and it is sold individually.

Correct good parts
The gaskets I ordered arrived in great shape and fit and worked perfect. I didn't realize until I went to your site and found there were 3 hardware versions for the model number I had. Your site had great illustrations to allow me to order the correct part the first time. Thank you

Head gasket had blown , from my lack of checking tightness of head bolts on a regular basis
Removed head and valve body and cleaned surfaces good and replaced with new gaskets and torqued head bolts to proper tightness... will check torque monthly now . hopefully avoid this from happening again ...
Turn power to compressor off. Remove and disassemble the head assy. Remove valve plate and valves. Clean off old gaskets. Reassemble and reinstall. Power on and test run. System is back to proper operation.
Pulled head and valve plate. Throughly cleaned valve plate, head and cylinder faces. Replace valves and gaskets. Installed new pressure gauge. Works like new. Did change oil after flushing base,

A Bit Difficult
Total Repair Time:
More than 2 hours
Tools:
Pliers, Screw drivers, Socket set, Wrench (Adjustable), Wrench set
Removed the 6 head bolts
Removed old gaskets from head and valve plates
Removed and replaced reed valves
Installed new gaskets and reinstalled head bolts
Very simple. Unbolt head, Carefully clean the gasket surface. This is aluminum, and care should be taken to not damage the surface and the little ridge that runs around the gasket perimeter. I replaced the valve body gasket and the intake and exhaust valves as preventative maintenance.
