I am having a hard time meeting the protection requirements outlined in the manufacturer's specifications. I'm installing HomeFlex CSST in California - California's plumbing code defers to the manufacturer for most of the installation requirements for CSST.
HomeFlex requires that horizontal runs through studs have 5" of protection on either side of each stud through which it passes (when it is within 2" of the edge, inevitable when dealing with 2x4s). However, HomeFlex does not provide a branded product to accomplish this (which is generally preferred, as mixing/matching brands in the same CSST install is usually a show-stopper for inspections), and I am unable to find anything of sufficient dimensions @ 16 gauge hardened steel that meet the requirements for protecting CSST.
At this point, the only 2 options I can see to meet the requirements established by HomeFlex, are to either fabricate my own striker plates or to find the odd-sized 1-1/4" steel pipe that is noted as an acceptable alternative, and cut it to 11-1/2" lengths (5" + 1-1/2" + 5"). Are these really my only options (other than ripping it out and using black pipe)? What are others doing to address this requirement?
Here's the relevant part of the documentation (full doc is here):
Update: I have found some products on the horizon from other CSST manufacturers (namely Gastite), however these, made by any brand, do not appear to be yet available for sale from anywhere:
