Enginetech Valve Stem Seal Positive VITON

Enginetech Positive VITON valve stem seals (also called valve stem oil seals) help keep engine oil from seeping down the valve guides and into the intake and exhaust ports. They are made for engine rebuilders who want a durable seal that holds up to heat.

Key Features:

• Viton elastomer sealing lips: the high-temperature material resists heat, oil and chemicals.
• Metal-clad positive design: the seal grips firmly and controls the oil that reaches the valve stem.
• Wide stem tolerance: Enginetech designs its Premium Positive seals to work with valve stems from 0.005 in. under to 0.015 in. over.
• Helps preserve parts: the design can reduce the need for valve guide replacement, so you can ream a worn guide instead.
• Simple installation: the seals suit standard engine rebuild procedures.

Enginetech builds its valve stem seals with OE-type or better materials, not low-grade nitrile. These Positive VITON seals give engine builders a reliable way to control oil consumption and help extend engine life.
