2 in (50 mm) Natural Rubber Gasket, BS4504 PN10/16 | LG1650
Available
This AAP natural rubber insertion gasket is drilled to BS4504 PN10/16 (manufacturer-stated) and is supplied in 5 sizes from 2 in (50 mm) to 6 in (150 mm), all 3 mm thick.
AAP makes it from commercial-grade natural rubber with cotton reinforcement for general-purpose sealing of flanged joints. It is a full-face gasket drilled for the flange bolts, and the outside diameter, bolt circle and hole size match AAP's BS4504 PN16 plate flanges.
AAP lists a hardness of 70 Shore A, a maximum temperature of 65 °C and applications in air and water. Resistance to oils, petroleum products and acids is poor, and organic solvents are not recommended.
Where this product is used
- Air and water lines at ambient temperatures
- General-purpose sealing of flanged joints

Selecting the right option
Natural rubber suits air and water. Choose a different material for oil, fuel, hydraulic fluid or solvent duties, where the NBR non-reinforced gasket is the better fit. AAP lists low-pressure steam among the applications for this rubber but also gives a maximum temperature of 65 °C, so confirm the operating temperature with AIMS before using it on any steam duty. AAP's catalogue does not give a pressure rating for natural rubber gaskets, and the joint rating is set by the flanges, so check your design pressure with AIMS if you are unsure. This range covers 2 in to 6 in only, so check the size you need is listed before ordering.
