Full product description
CMA 11-Hole Boiler End-Cap Gasket Black paper composite boiler end-cap gasket for CMA (Astoria) boilers, sized to seal the end-cap flange and its eleven mounting/probe holes. SPECIFICATIONS 190 x 137 x 3 mm 11-hole pattern Black paper composite material COMPATIBILITY Fits: CMA (Astoria) boiler end-caps using the 11-hole, 190 x 137 mm pattern INSTALLATION Straightforward DIY replacement when the end-cap is already off, but boiler disassembly itself should be done by a qualified technician. PRO TIPS Always install a fresh gasket rather than reusing the old one, paper composite gaskets compress permanently once torqued and will leak if reinstalled. Snug end-cap bolts evenly in a crisscross pattern to seat the gasket without warping the end-cap.
