SFI-spec stainless steel tubing for use with SFI 17.1 rated systems. Tubing is 5/16" (8mm) and pre-cut in lengths of 9.5ft / 3m.
Aluminum tubing is our preferred tubing for SFI systems due to it's easier nature of bending for installation compared to steel tubing. However, some sanctioning bodies require steel tubing be used in SFI-spec systems in order to be compliant with the rules. Please consult your rulebook to confirm requirements.
