Frequently Asked Questions

Q: How do I know which cylinder size fits my oil-free air compressor?

A: Match the size to your compressor's rated wattage. The 63.5×69×24.5 mm fits 550–600W models, 63.5×69×47.5 mm fits 750–980W, 63.5×69×50 mm fits 1100W, and 69×75×47.5 mm fits 1500–1600W compressors. If unsure, measure your existing cylinder's outer diameter, inner diameter, and height before ordering.

Q: What is included in each set?

A: Each set includes 2 pieces — one oil-free cylinder and one piston ring — providing everything you need for a complete cylinder head replacement on compatible oil-free air compressors.

Q: Is this cylinder compatible with oil-lubricated (oiled) air compressors?

A: No. This replacement kit is specifically designed for oil-free (oil-less) air compressors. Using it in an oil-lubricated compressor is not recommended, as the rubber material and sealing design are optimized for oil-free operation.

Q: How difficult is it to install the cylinder and piston ring?

A: Installation is straightforward for those comfortable with basic tool maintenance. You will need to remove the compressor head, swap out the old cylinder and piston ring, and reassemble. Always disconnect the compressor from power before performing any maintenance work.
