Genuine Speedaire Compressor Parts for Every Model
Keeping a Speedaire compressor running at peak performance starts with using the right parts. Genuine Speedaire replacement parts are engineered to fit and perform exactly like the originals, so repairs go smoothly and downtime stays short.
Speedaire Replacement Parts That Fit Right and Last
A compressor is a long-term investment. Using correct replacement parts when something wears out is the best way to protect that investment and avoid repeat repairs.
The Speedaire parts catalog covers every major component: pump assemblies, pressure switches, check valves, unloader valves, safety relief valves, gaskets, piston rings, belts, and complete repair kits. Parts are available for both current production models and many older discontinued units.
Pressure switches control when the compressor starts and stops. A faulty pressure switch is one of the most common reasons a compressor behaves erratically. Replacing it with a genuine part ensures the cut-in and cut-out pressures are calibrated correctly from day one.
Belts on belt-drive compressors stretch and wear over time. A loose or cracked belt reduces efficiency and puts extra load on the motor. Replacing it on schedule prevents more costly pump or motor damage down the line.
Check valves prevent air from flowing back into the pump after the motor shuts off. When a check valve fails, the motor has to start under load, which shortens its lifespan significantly. It is a small part with a big impact on compressor longevity.

Speedaire Compressor Parts FAQ
Locate the model number on the nameplate of the compressor, usually found on the tank or motor housing. Use that number to search for compatible parts. Grainger and authorized Speedaire distributors maintain parts diagrams and cross-reference tools that match parts to specific model numbers.
Yes. Speedaire and Grainger stock parts for many discontinued models in addition to current production units. If a direct replacement is no longer available, a compatible substitute can often be identified using the original part number.
Inspect the belt every three to six months depending on usage. Look for cracking, fraying, glazing, or noticeable stretch. Replace the belt if any of these signs are present. A belt that slips or breaks during a busy workday can take the compressor offline at the worst possible time.
Short cycling, where the compressor turns on and off rapidly, is usually caused by a failed check valve or a leak in the air system. When the check valve fails, air bleeds back from the tank into the pump, causing the pressure switch to trip the compressor back on almost immediately. Replacing the check valve usually solves the problem.
Some components like pressure switches, relief valves, and air filters are compatible across brands as long as the specs match. However, pump-specific parts such as pistons, rings, and valves are designed for Speedaire pumps and may not fit other brands. Always verify specifications before substituting parts across different manufacturers.
