I presume you're referring to "CSST" (Corrugated Stainless Steel Tubing) products, such as Gastite, Omegaflex, Wardflex, etc. If so, the outer jacket can be stripped off with a razor knife, near a fitting, and a ground clamp can be applied, as long as it's not torqued down to the point where it crushes the corrugations. This will NOT effect the operation/integrity of the pipe, but will offer you a place to bond.

When I install this type of pipe, hoever, I usually enter the house with steel pipe, into a manifold, then branch out with CSST. I do know others, however, that run this stuff in from the meter. It's ugly, but permitted. [Linked Image]

It's all about integrity.
