FLANGE GASKET 4 BOLT CENTRE BORE 57.15 MM

FLANGE GASKET 57.15 MM BORE WITH 4 X BOLT HOLES 1.3 MM THICK BORE SIZE 57.15 MM 4 x 12 MM BOLT HOLES Material consists of a tanged and galvanized steel core. An asbestos- free soft material compound containing aramide fibers, inorganic fillers and high- grade binder elastomers is applied to both sides of the core. Properties exhibits very high mechanical strength together with very high pressure and temperature resistance, yet still conforms well to sealing surfaces. The material is resistant to oils, fuels, and mixtures of water and antifreeze or corrosion inhibitors. Application for cylinder head gaskets in standard IC engines for other sealed joints subjected to high mechanical and thermal stress, e.g. intake and exhaust manifolds, transmission flanges, and high- pressure pumps Approvals Germanischer Lloyd (DNV GL) Approval for shipbuilding Technical Data (nominal thickness 1.30 mm) Weight per surface unit kg/ m2 ≈ 3.8 Residual stress acc. to DIN 52 913 16 h, 300 °C N/ mm2 > 40 Compressibility and recovery acc. to ASTM F 36, procedure J compressibility % 7 - 13 recovery % > 55 Swelling acc. to ASTM F 146 in IRM 903 Oil (replaces ASTM Oil No. 3) 5 h, 150 °C increase in thickness % < 10 in water / antifreeze (50:50) 5 h, 100 °C increase in thickness % < 7 Operating temperature maximum °C 400 Surface pressure maximum at 300 °C N/ mm2 100
