Frequently Asked Questions
Q: How do I know which cylinder kit size is compatible with my oil-free mute air compressor?
A: Match the kit size to your compressor's wattage. The 63.5 × 69 × 24.5 mm kit suits 550W/600W models; 63.5 × 69 × 47.5 mm suits 750W/950W/980W models; 63.5 × 69 × 50 mm suits 1100W models; and 69 × 75 × 47.5 mm suits 1500W models. For certainty, measure your existing cylinder bore and stroke dimensions before ordering.
Q: Does this kit work with oil-lubricated compressors as well?
A: This cylinder sleeve and piston ring kit is specifically designed for oil-free (oil-less) silent/mute air compressors. Using it with an oil-lubricated compressor is not recommended, as the internal dimensions and material tolerances are optimised for dry-running oil-free designs.
Q: What is included in this replacement kit?
A: Each kit contains 1 cylinder sleeve, 2 O-shaped gaskets, 1 catheter gasket, and 1 square gasket — everything needed to complete a standard cylinder sleeve replacement on a compatible oil-free mute air compressor.
Q: Is this a genuine OEM part?
A: This is an aftermarket replacement kit, not an OEM-branded part. It is manufactured to precise specifications to be compatible with a wide range of oil-free silent air compressors in the 550W–1500W power range.
