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.
