John Guest Fittings

In all applications, JG Super Speedfit fittings require no tools. Tubing is simply inserted into the fitting collets to effect a secure connection. Whether metal or plastic tubing is used, the integrity of the connection is assured - John Guest fittings are manufactured to the strictest tolerances. John Guest products processes employ statistical process control to ensure the absence of variation. John Guest designs provide superior flow characteristics and eliminate the need for sealant. Moreover, these fittings can be rescued repeatedly without the loss of connection integrity.
