Product Description

?

This is a genuine Craftsman part for use with Craftsman Air Compressors. The compression ring creates an airtight seal between the cylinder and piston and helps facilitate heat transfer between the piston and cylinder wall. The compression ring on a piston head is a wear and tear item. It is, often, a cause of an air compressor failing to produce air. This part is sold individually. Unplug the air compressor and bleed air from the tank before installing this part. Wear work gloves to protect your hands.

What a change!
I can see now, I've needed this part for a while. While in normal use it used to take about 7 minutes to recharge my air system, now it takes 3. Great to have this service - most of these parts are no longer available from Craftsman.

The parts arrived very promptly, when I installed them in my air compressor it now runs like new! I though I was going to have to buy a new Air compressor, but now I think it will be good for another 18 Years!
