Product Information

Description:

O-rings are made to contain thousands of PSI pressure by creating a seal between two or more parts. O-ring measurements are defined by the inside diameter and the thickness.

There are many causes for O-Ring failure. The most common among power tools are:

Extrusion and Nibbling

The O-ring has ragged, tattered edges. These are commonly caused by pressure spikes which shear off tiny “bites” from the o-ring, or caused by clearance gaps.

Abrasion

One or both sides of the o-ring appear rough and slightly flattened. Commonly caused by a contact surface that it too rough, contains grit or is too smooth to allow lubrication.

Over Compression

The O-ring is flattened on both sides and may have a “ring” split along its length. Commonly caused by excessive pressure or heat.

Heat Hardening

The O-ring has a pitted or cracked surface, and is often flattened on both sides. Caused by temperature exceeding o-ring capacity.

Weather/Ozone Cracking

The O-ring is covered in small surface cracks. Caused by exposure to ozone, UV rays and air pollution. Excessive seal stretching (greater that 5%) causes similar cracking.

Warning: California's Proposition 65

I think what happen was. Over time. Two of the head bolts came loose. Causing two of them to break off. Which caused to of the o rings to break.

Was able to unscrew the two broken bolts. Replaced the 2 o rings with new ones. And installed two new bolts. The compressor is working like brand new. Pressure builds up to 120 psi. Now. And stays there.

35 year replacement part

Compressor valve block was not sealing. This o-ring was enlarged after years of use and found this replacement on eReplacementParts.com. Back in service in just a few days.

Guest - April 26, 2022 Verified Purchase

Brought my Crafstman Air compressor 919167312 back to life!

I bought this o-ring along with the compression ring and the filter kit. We had the filter for a long time, but without the housing it kept falling out and we eventually lost it. The compressor started to sound bad and eventually didn't build up any compression. Took it apart and the compression ring was all bent and the piston had some serious play inside the cylinder. The cylinder was fine though. There were no nicks or grooves inside.

Hard to find parts

This was part of an overhaul kit for an older Craftsman compressor. Parts are hard to find, but eReplacements had them. All arrived on time and in good shape. Everything was the correct size and went together well. Great company; highly recommended.

Guest - January 19, 2022 Verified Purchase

Precisely what was needed

Fit up was exactly right. Web site made it easy to find the correct parts. Quality was better than the last place I bought parts from. I will order from ereplacementparts again.

Guest - September 3, 2021 Verified Purchase

Easy repair, the part did not match the model number had to reorder using size pattern which helped a lot.

The parts arrived promptly and machine is running great. Have found parts for craftsmen equipment with your company that I couldn't find any where else.
