Engine Valve Cover Gasket
Engine valve cover gaskets and spark plug tube seals - oil and heat resistant rubber seals for overhead cam and pushrod engines.
The valve cover gasket seals the top of the cylinder head, where oil is thrown around by the camshaft and temperatures cycle from cold start to full operating heat several times a day. A rubber gasket that holds its shape through that cycle prevents both oil weeping and the vacuum leaks that follow a hardened gasket.

Sizes and materials
Compounds are selected for continuous hot-oil contact, typically nitrile or ACM, with silicone and FKM options for higher running temperatures.
Quality control and inspection
Every production lot is checked for lip geometry, spring tension, case concentricity and rubber hardness, then inspected visually for flash, voids and flow lines before packing. Inspection results are recorded against the batch, so any shipment can be traced back to the lot it came from.
