C4430 is a high quality general purpose gasket material manufactured from compressed synthetic and glass fibres that are bound with a NBR (Nitrile) binder. The material has outstanding stress relaxation properties and excellent resistance to air, water, oil, fuel, gas and a wide range of chemicals. It is finished on both sides with a 3XA anti-stick coating which aids with flange separation and reduces installation time. It also removes the need for application of grease or sealants which may result in failure of the gasket.

C4430 Gasket Material carries a range of international approvals for use in specific applications. These include (but are not limited to) AGA Certification to 4623-2008 Class III, Pressure 2 MPa, AS4020 (Products for use in contact with drinking water), Approval for gas supply in accordance with DIN3535/6, WRC Approval (Water Research Council, UK), Germanischer Lloyd General Shipping and Firesafe to BS5146.
