919150380 Craftsman Compressor - Overview

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. Thes...Read moree 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.

This is an authentic OEM part. The filter is used with air compressors from Porter Cable, DeVilbiss, and Black & Decker. The foam filter is used to prevent dirt and debris from entering and potentially damaging the pump. A hex driver, or screwdriver may be needed to install this item and it is sold individually.

This rod kit is an original part from Craftsman for air compressors. This part attaches to the piston to the crankshaft that is in the pump.

This authentic manufacturer-sourced part which is specially designed for use with Craftsman equipment. The ball bearings are generally utilized to reduce the friction between rotating parts. The balls or rollers take the load and spin, distributing the weight evenly while the minimal contact area of the ball reduces friction.

Keep in mind this high-quality bearing is made of durable metal and is sold individually.

This is a manufacturer approved replacement muffler used on air compressors. Muffler softens the noise coming from the engine and provides an additional filtering. This Kit includes the Plastic Filter Holder, Foam Filter, Two (2) Plastic Pins used to attach it and a Metal Mesh Screen.
