This authentic manufacturer-sourced gasket kit is made for use with Craftsman air compressors. The parts in this kit are utilized to ensure a tight fit between the pump's components allowing it to build up the pressure. Over time gaskets may wear out and begin to crack eventually requiring replacements. For the exact locations and the correct installation of the new components, please refer to the appropriate diagrams of your model. This high-quality kit includes five durable parts. You will need a wrench set to take the pump apart and reassemble it.

Air coming out of filter. and will not build pressure.

asked on 2023-03-08
Hi Ed,
Thank you for your question. If your air compressor will not build pressure, there are some parts that you will need to check to see which one is causing the issue. We recommend checking the gaskets, the valve reed, the filter and the intake filter. Once you have determined the part you need, please call customer service. We look forward to hearing from you!

Tools Used

Parts Used
Remove the four allen bolts and pay close attention to how each part comes off; the order of arrangement. Clean old gasket material with a small straight edge to prepare surfaces for new gaskets. Replace each part with new gasket in reverse order of how it was removed. Replace the head bolts and HAND tighten very firmly. I would not advise a ratchet or torque wrench. Just use firm, even hand pressure in a cross pattern Use a small amount of Vaseline petro. jelly to hold reeds in place. I used NO gasket glue for reassembly. Compressor runs like a new one.

The gasket kit that ereplacement stocked saved me from having to spend $400.00 on a new compressor. The kit was complete and it took about 30 minutes to install after replacing the gaskets and turning on the compressor it came up to full pressure. The kit was very good quality and shipping was fast.
Simply remove the cylinder head, then line up the gaskets how the go on the compressor, and place them on. Then replace the cylinder head.
