T4,T5 Valve Collet - 7mm Stem Valves

This replacement valve collet is designed for Volkswagen engines using 7mm valve stems, making it suitable for a wide range of T4 and T5 Transporter engines, as well as many other VW petrol and diesel models. Valve collets (also known as valve keepers) are a critical part of the valve train, locking the valve spring retainer securely onto the valve stem.

Each valve uses two collets, which fit into the grooves on the valve stem and clamp the retainer in place. This ensures the valve spring maintains correct tension and keeps the valve seated and operating accurately. Worn, damaged, or mismatched collets can lead to improper valve seating, loss of valve control, or serious engine damage, so replacement is strongly recommended during cylinder head rebuilds or valve train servicing.

Manufactured to high-quality standards, these collets are precision-made to ensure a secure fit on 7mm valve stems. They are suitable for both petrol and diesel engines and provide reliable long-term performance under normal and high-load operating conditions.

These valve collets are sold individually, allowing you to purchase exactly the quantity required for your engine rebuild or repair.
