Stage X Billet Tumbler Generator Valve (TGV) O ring Seal

Stage X Billet TGV (Tumbler Generator Valve) O-Ring Seal

This is a replacement sealing component designed specifically for Stage X billet Tumbler Generator Valve (TGV) housings. It gives a reliable, leak-free seal between the TGV assembly and the cylinder head on Subaru EJ series engines.

It is made from a durable, oil- and heat-resistant elastomer to withstand the thermal and chemical conditions of a high-performance engine bay.

Key features

• Precision fitment: made for Stage X billet TGV housings, for correct sealing and easy installation.
• High-temperature resistance: withstands extended exposure to high engine bay temperatures without deforming or breaking down.
• Oil and chemical resistance: resists swelling and deterioration when exposed to engine oil, fuel and cleaners.
• Leak prevention: keeps a consistent seal under pressure, helping to prevent vacuum or boost leaks.

Recommended use

• When installing or replacing Stage X billet TGVs
• During routine maintenance or intake manifold servicing
• Whenever the TGV assembly is removed or refitted

Compatibility

• For Stage X billet TGVs on Subaru EJ engines
• Not suitable for OEM plastic or other aftermarket TGV housings

Tip: always inspect the mating surfaces and replace the O-rings during reassembly for a proper, long-lasting seal.
