REPLACEMENTKITS.COM Valve Stem Seals 4-Pack for Kohler Small Engines — Viton, OEM Fit

If you need leak-resistant valve stem seals that match OEM fitment for several Kohler small engines, this 4-pack delivers durable Viton construction and broad model compatibility. Each seal is sized to replace common OE part numbers such as 12-032-02, 66 032 05-S and Stens 055-006, providing a straightforward option for routine engine maintenance or repair.

Which engines and part numbers do these seals fit?

They are engineered to fit a wide range of Kohler single- and twin-cylinder small engines used in lawn tractors, mowers, and similar equipment. Use the model list to confirm fitment or compare against your engine's original part number.

• Compatible with CH, CV, ECH and ECV series models like CH18, CH23, CH730, CV640, CV740, ECH630, ECV740E, and more.
• Replaces OE numbers: 12-032-02, 66 032 05-S, 24 032 05-S, and aftermarket Stens 055-006.
• Intended for small Kohler engines commonly found in residential and commercial outdoor power equipment.

How does the Viton material benefit engine performance?

Viton is a synthetic fluoroelastomer noted for resisting heat, oil, and fuel exposure better than standard rubber. That resistance helps the seals keep a tighter seal under higher temperatures and extended service intervals.

• Improved resistance to oil and fuel breakdown compared with generic rubber seals.
• Handles typical small-engine operating temperatures without rapid hardening or cracking.
• Helps reduce valve guide leakage and associated smoking or oil consumption.

What’s included and how many replacements come in a pack?

The product comes as a convenient four-piece set so you have spares for both valves on single-head engines or a reserve for later service. The quantity is useful for quick repairs and planning routine maintenance without ordering multiple times.

• Four internal valve stem seals per package.
• Enough seals for many single-cylinder heads or to keep as spare parts.
• Packaged for storage until installation; no additional components included.

Are these seals a true direct replacement for OEM parts?

Yes, these are manufactured to match the dimensions and function of the referenced OEM and aftermarket part numbers. They are offered as aftermarket replacements by an American-owned company that backs quality with a satisfaction policy.

• Designed to match OE fit and sealing profile for listed Kohler models.
• Sold by REPLACEMENTKITS.COM with a stated satisfaction guarantee.
• Suitable for routine servicing and field repairs when OEM parts are unavailable.

Who is this for: This 4-pack is aimed at DIY mechanics, small engine repair shops, and equipment owners who need reliable valve stem seals for Kohler-powered mowers, utility tractors, and other outdoor machines.
