Description: Marine Hatch Cover Gland Packing in Natural Rubber , which is an excellent material for general purpose use. The rubber core has a strong solid skin to reduce damage on the packing surface, and is fabricated from a strong natural rubber offering the best compression and a minimum wear.Inside core is excellent elastic rubber, braid-over-braided by chemical resistant synthetic fibres & P.T.F.E fibres. It has excellent sealability & elasticity even under low seating stress,a little deformation for repeated use. Application: Marine Hatch packing is used to achieved weather-tightness and sealing in various applications. Hatch packings are UV radiation resistant and applicable in a wide temperature ranges. Packing is used exclusively for hatch cover. Also used for watertight doors, skylights, ullage plugs and other marine applications. Advantages: Can reduce friction Easier sliding with a minimum wear Has weather-tightness and sealing Not easily deformed by repeated use.
