These speedfit quick connect valves use push-fit technology. The quick disconnection makes installation easy without the need for any tools. This valve has a 1/4 turn from open to closed. These valves are manufactured in white polypropylene with food grade EPDM 'O' Rings for use with potable water. For use with other potable liquids, please refer to our Customer Services department for guidance. The valves have high chemical resistance, but are not suitable for air or inert gases. Hence, these are not to be used with compressed air, explosive gases, petroleum spirits and other fuels or for heating systems.

This fitting is made of the following components:

The body is produced in polypropylene
O-rings are EPDM
The collet is produced in polypropylene with stainless steel teeth
The handle is produced in acetal copolymer

National Pipe Thread (NPT) Size Measured Against a Ruler*
Actual Diameter (Inches)	National Pipe Thread (NPT) (Fractional)
0.405"	1/8"
0.540"	1/4"
0.675"	3/8"
0.840"	1/2"

*NOTE: A very common misconception is that a 1/4" NPT measures as 1/4 inch on a ruler or tape measurer. However, that is not the case. NPT will measure larger in diameter. Above is a sizing reference to help clarify.
