John Guest - Polypropylene Fixed Tee Adapter Quick Connect Fitting - White
Polypropylene Fixed Tee Adapter Quick Connect Fitting
The John Guest fixed tee adapter combines two quick-connect OD ports with one male NPT threaded connection, enabling seamless integration between push-fit tubing and traditional threaded components. Manufactured from polypropylene with food-grade nitrile O-rings, this fitting is designed for potable water, air, inert gases, and vacuum applications. Push, turn, and you're done.
Engineered for Speed and Reliability
Grip-Then-Seal Collet
John Guest's proven collet design grips the tube first, then seals with an O-ring. No tools required for installation, and demounting is just as simple with a press-and-pull action.
Food-Grade Materials
Acetal copolymer body with nitrile O-ring meets food safety standards for potable water and beverage lines, including CO2 systems for carbonation and draft applications.
NPT Thread Integration
One male NPT thread side allows direct connection to taps, filters, valves, or other threaded fittings. Two quick-connect sides accept OD tubing for flexible routing.
UK Manufacturing
Designed, manufactured, and assembled by John Guest Speedfit in the United Kingdom with strict quality control for consistent performance across installations.
Reusable Connection
Unlike compression fittings or crimp rings, the collet system allows you to disconnect and reconnect tubing without damage to the fitting or line.
Multi-Application Use
Suitable for potable water, air lines, pneumatic controls, vacuum systems, and inert gases. One fitting platform for diverse installation needs.
Understanding National Pipe Thread Measurements
NPT sizes do not measure as their fractional name suggests. A 1/4" NPT thread measures approximately 0.540 inches in actual diameter when measured with a ruler, not 0.250 inches. This is a common source of confusion. Reference guide: 1/8" NPT measures 0.405" actual diameter, 1/4" NPT measures 0.540", 3/8" NPT measures 0.675", and 1/2" NPT measures 0.840". Always verify thread size with calipers or the chart above before ordering to ensure proper fit with your existing components.
Where This Fitting Works
John Guest polypropylene fixed tee adapters are compatible with reverse osmosis systems, under-sink water filters, refrigerator ice makers, beverage dispensers, pneumatic controls, CO2 carbonation lines, and vacuum applications. Use with John Guest tubing in corresponding OD sizes. Common applications include connecting filtered water lines to faucets, branching supply lines to multiple appliances, and integrating quick-connect tubing with NPT-threaded valves or manifolds. Suitable for potable water and food-contact applications.
John Guest fittings are the standard in push-to-connect reliability for water treatment professionals and DIY installers worldwide.
