We recently brought in the new generation of CSST with a Black jacket.

STANDARD-FLEX Corrugated Stainless Steel Tubing or CSST is great for installation of gas appliances. CSST easily snakes into attic and basements areas, around corners and bends, and through walls.

Certification through manufacturer is required before installing CSST.

Now we are selling STANDARD-FLEX at least 40% less in pricing compared to top 4 CSST Sellers with equal quality.
