Highly effective, super-fast gas piping solutions for appliances
The Brymec CSST Range provides the fastest, most efficient solution for gas piping in all building types, including those with tight spaces and unvented voids.
Exceptionally flexible and easy to install, it delivers a cost- and resource-effective solution on site and longer-term performance with lower lifetime maintenance needs.
Maximising efficiency and reliability
CSST Duo Sleeve
For gas services installed within unvented voids — such as floor voids, shafts and service ducts — any potential gas escape must be safely contained and vented to a safe space. CSST Duo simplifies this requirement with a factory‑assembled integral containment sleeve, removing the need for secondary sleeving or specialist conduits.
When installed correctly, the sleeved system safely contains any gas escape, reducing installation complexity while supporting compliance.
