M14 x 1.5 Quick Connector Set – Leak-Proof Pressure Washer Fittings

Q: What thread size is this quick connector fitting set?

This fitting set uses the standard M14 x 1.5 thread — the male connector has a 14 mm outer thread and the female connector has a 14 mm inner thread. This is a widely used size that fits most pressure washer hoses, spray guns, nozzles, and garden water pipes without needing any additional adapters.

Q: Is this connector set compatible with my pressure washer?

In most cases, yes. The M14 x 1.5 thread is a universal standard size compatible with the majority of mainstream pressure washers, garden hoses, and car-washing equipment available today. We recommend double-checking your existing hose or gun thread specification before purchasing to confirm compatibility.

Q: What is the maximum pressure this fitting can handle?

This quick connector set is rated for pressures under 850 kPa, making it well suited for domestic and semi-professional pressure washing, car detailing, and garden irrigation tasks.

Q: Do I need any tools to connect or disconnect these fittings?

No tools required! The push-in quick-release design and knurled non-slip grip allow you to connect and disconnect in about one second using just your hands, saving time when swapping nozzles or accessories frequently.

Q: What is the difference between the stainless steel and brass female connectors?

Both are included in the full set. The stainless steel female connector excels in high-humidity and chemically aggressive environments due to its superior corrosion resistance. The brass female connector offers excellent wear resistance and is ideal for high-frequency connection cycles. Having both gives you flexibility across a wide range of applications.
