HOW SUPER SPEEDFIT WORKS
To make a connection, the tube is simply pushed in by hand; the unique patented John Guest collet locking system then holds the tube firmly in place without deforming it or restricting flow.
Materials of construction
Super Speedfit fittings are made up of three components:
Bodies are produced in an acetal copolymer or polypropylene.
‘O’ rings are Nitrile rubber or EPDM.
Collets are produced in acetal copolymer or polypropylene with stainless steel teeth.

Maximum Torque Values for Plastic Threads BSP, BSPT & NPT.
Plastic threads are not generally as strong as brass threads. Customers and end users should be aware of this when choosing products for their applications. Over-tightening of plastic threads will cause undue stress and eventual cracking and leakage. The maximum torque figures for BSP and BSPT threads used in John Guest fittings in mating threads conforming to the relevant BS or International thread standards are shown below.
1/8 – 1/4
3/8 – 1/2
