919152921 Craftsman Compressor - Parts

When using an air compressor, moisture naturally builds up inside the tank as air is compressed. If this water isn’t drained regularly, it can lead to internal rust and damage over time. That’s where the drain valve comes in—it allows you to release the built-up water and keep your tank in good condition. Located at the bottom of the tank...Read more, this valve should be opened after each use to prevent corrosion and extend the life of your compressor. If you tend to leave air in the tank for long periods, water accumulation can be even more significant. This replacement drain valve features a thread size of 18 TPI and is sold individually. Regular maintenance with a working drain valve helps ensure safe and efficient compressor operation.

This saddle mount cup is an OEM direct from Craftsman for air compressors. This part holds the screw in place. You will need a wrench to remove the bolts that go through it. It is recommended that you wear gloves when replacing this part. This saddle mount cup is made of steel and sold individually.

This safety valve is a genuine replacement part manufactured for use with air compressors. If the compressor's pressure switch malfunctions and does not turn the motor off when the amount of pressure is met, the safety valve will open to release the extra air pressure. The amount of pressure required to open the safety valve is set by the...Read more tension of the spring inside the valve. The spring can wear out, and leave the valve open at a lower pressure than what is set to turn the switch off, and will not allow pressure to build inside the tank. Please make sure to refer to the appropriate diagrams of your model for the correct location and application of this component. Keep in mind this high-quality part is made of durable metal and is sold individually.

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. rnrnThere are many causes for O-Ring failure. The most common among power tools are: • Extrusion and Nibbling - The O-ring has ragged, tattered edges. ...Read moreThese 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 a genuine OEM part that is intended to be used with air compressors from Porter Cable, DeVilbiss, and Black & Decker. The regulator is used to adjust the level of pressure in the tank. This item is sold as an individual replacement part.
