John Guest - Polypropylene Inline Straight Ball Valve - Threaded
Polypropylene Inline Straight Ball Valve - Threaded
The John Guest inline straight ball valve combines Speedfit push-fit technology with threaded NPT connections for fast, reliable shutoff control in water filtration and treatment systems. Quarter-turn operation lets you open or close flow instantly without tools, while food-grade materials ensure safe use with potable water and other approved liquids.
Built for Potable Water
The valve body is manufactured in white polypropylene with food-grade EPDM O-rings, a polypropylene collet with stainless steel teeth, and an acetal copolymer handle. This combination provides high chemical resistance while maintaining compatibility with drinking water standards. The push-fit design allows quick disconnection without wrenches or special tools, reducing installation time and simplifying maintenance.
Understanding NPT Measurements
National Pipe Thread sizing does not match ruler measurements. A 1/4" NPT valve actually measures 0.540" in outer diameter, not 0.25". Reference: 1/8" NPT = 0.405", 1/4" NPT = 0.540", 3/8" NPT = 0.675", 1/2" NPT = 0.840". Measure your existing fittings with calipers or compare against the chart above to confirm compatibility before ordering.
Approved Applications
This valve is designed for potable water systems and other approved potable liquids only. It is not suitable for compressed air, inert gases, explosive gases, petroleum spirits, fuels, or heating systems. Consult John Guest Customer Services for guidance on specific liquid compatibility beyond standard drinking water applications.
