John Guest protective spring for 3/8" tube
Flexible protector to reinforce a 3/8" (9.5 mm) tube line in areas where the run may create a tight bend or repeated flexing.
What it’s for
Helps spread the bend over a greater length of tube and reduce the risk that a localized bend will cause kinking or stress next to a connection.
Installation
Place the spring in the area that needs protection before finally closing the run. It must not be used to force the tube to adopt a bend radius that is incompatible with the installation.
Frequently asked questions
What tube does it use?
3/8" (9.5 mm).
Does it replace an elbow?
Not always; if the change of direction is very sharp, an elbow may be more appropriate.
Does it prevent all kinks?
It helps protect the tube, but the run must be properly designed.
Where is it useful?
Near equipment, outlets or areas subject to bending.
