The Tee Cap with Drain Ø 125 is an essential component for effectively sealing the bottom or unused end of a 90/135 degree tee in your flue system. This versatile tee cap is engineered to work with solid fuel, gas, and oil appliances, such as woodstoves, gas coal effect fires, and boilers. Constructed with an outer 304-grade stainless steel skin and an inner 316-grade stainless steel skin, each 0.4mm thick, it promises durability and efficiency.
The cap features a density of 200kg/m3 of compressed rockwool insulation to ensure optimal thermal performance while maintaining a safe 50mm distance from combustibles. Fully welded for strength, the TWPro range is HETAS approved and CE marked, meeting stringent safety standards (EN1856-1 T600 N1 W V2 L50040 G50 and EN1856-1 T200 W V2 L50040 O20). Installation is seamless with a secure Locking Band mechanism, making maintenance, such as chimney sweeping, straightforward due to the 10mm threaded drain connection for carrying away excess condensate.
