John Guest - Acetal Female Connector Quick Connect Fitting - Grey British Standard Pipe Thread (BSPT)
Acetal Female Connector BSPT Threading
Push-fit female connector with British Standard Pipe Thread for secure, tool-free connections in potable water, air, and CO2 applications
Grip-then-Seal Collet Design
Collet Lock System
Grip-then-seal collet arrangement ensures a leak-proof connection. Push fully onto pipe, turn onto thread, and the fitting locks securely without tools or tape
Acetal Strength
Acetal copolymer construction offers superior strength and heat resistance compared to polypropylene. Food-grade nitrile O-ring rated for potable water and foodstuff contact
Tool-Free Installation
Speedfit push-fit design eliminates the need for wrenches, sealants, or specialized tools. Demount by unlocking the nut, pushing the collet toward the body, and pulling the pipe
Multi-Application Use
Suitable for potable water, air, inert gases, CO2 lines, pneumatic applications, and vacuum systems. Ideal for connecting taps, toilets, and filtration equipment
BSPT Thread Sizing Reference
| BSPT Size | Actual Diameter | Measured on Ruler |
|---|---|---|
| 1/8" BSPT | 0.383" | Larger than marked |
| 1/4" BSPT | 0.518" | Larger than marked |
| 3/8" BSPT | 0.656" | Larger than marked |
| 1/2" BSPT | 0.825" | Larger than marked |
Note: BSPT threads measure larger than their fractional designation. A 1/4" BSPT fitting does not measure 1/4" on a ruler.
Tubing and Pipe Materials
John Guest Acetal Female Connector with BSPT threading is compatible with PEX tubing, copper pipe, and plastic tubing. Designed for use in UK and European plumbing systems utilizing British Standard Pipe Thread.
