Air Hose Quick Release Coupler Set — Male & Female Compressor Fittings

Match the coupler size to your hose's inner diameter. The 20mm (≈3/4") variants are generally suited for smaller hose connections; 30mm (≈1-3/16") for mid-range; and 40mm (≈1-9/16") for larger hose runs. When in doubt, measure your hose's inner bore and check your compressor's port size before selecting a variant.

These codes typically refer to different coupler body profile series. Each profile (PP, PH, PM, PF) has a corresponding male plug and female socket that are designed to mate only with each other — PP male connects to SP female, PH male to SH female, and so on. They are generally not cross-compatible between series.

These fittings are generally suitable for covered workshop and garage environments. For prolonged outdoor exposure or high-humidity conditions, inspect fittings regularly for wear or corrosion. Contact us to confirm the material and finish for your specific series if corrosion resistance is a priority.

Working pressure varies by size and series. In most cases, quick release couplers in this class are designed for standard workshop compressors typically operating between 90–150 PSI. See variant options or contact us to confirm the rated pressure for your specific size and series before use in pressure-sensitive applications.

Yes — each set includes one male plug and one matching female coupler body. For example, selecting PP20+SP20 gives you one PP20 male plug and one SP20 female socket. The Qty option lets you choose 1, 2, or 5 complete sets.

These couplers are designed for standard air compressor hose connections. However, the PP, PH, PM, and PF profiles are not universally interchangeable — each series only mates with its own matching socket. Check your existing fittings' profile type and hose size before ordering to ensure a compatible match.

To connect: push the male plug firmly into the female coupler until you feel or hear it click into place. To disconnect: pull back the release collar on the female coupler while pulling the male plug out. Always depressurize the air line before disconnecting to prevent injury or sudden hose movement.
