John Guest - Polypropylene Male Connector Quick Connect Fitting - White
Polypropylene Male Connector Quick Connect Fitting
Push-to-connect NPT fitting engineered in the UK for secure, tool-free connections on water lines, CO2 systems, and pneumatic applications
Grip-and-seal collet design for reliable connections without tools
Collet Grip Technology
John Guest Speedfit collet grips the tube, then seals with a food-grade nitrile O-ring. Push fully onto pipe and turn onto NPT thread for secure connection.
Food Grade Materials
Polypropylene body with food-grade nitrile O-ring meets potable water standards. Safe for drinking water, foodstuff contact, and beverage applications.
Tool-Free Installation
No wrenches or crimping required. Push tube into fitting until seated, then hand-tighten onto NPT thread. To disconnect, push collet and pull tube.
Versatile Application
Suitable for potable water, air, inert gases, CO2 lines, pneumatic systems, and vacuum. Polypropylene offers reliable performance across common plumbing needs.
Understanding National Pipe Thread measurements
NPT threads do not measure as their fractional name suggests. A 1/4" NPT thread actually measures 0.540" in diameter on a ruler. Use the reference below to identify your fitting size correctly: 1/8" NPT measures 0.405", 1/4" NPT measures 0.540", 3/8" NPT measures 0.675", and 1/2" NPT measures 0.840" actual diameter.
Ideal for taps, toilets, RO systems, and appliance connections
John Guest male connectors work with all John Guest Speedfit tubing and fittings. Commonly used to connect water filtration systems, reverse osmosis units, refrigerator lines, ice makers, beverage dispensers, pneumatic controls, and CO2 gas systems. The NPT male thread connects to any female NPT port on appliances, valves, manifolds, or fixtures.
