Unique CPV Tool Protects Replacement O-Seal Stem Seals During Installation.

Every new CPV O-Seal valve provides leakproof assurance to 6000 psi. Properly maintained they should provide long, reliable service. The stem seals are made of ethylene propylene, polyurethane, DuPont Viton™, etc. and should be inspected at appropriate intervals depending on system conditions and frequency of use.

To maintain CPV’s leakproof standard after stem seal replacement, the “U” cup installation tool developed by CPV should be used. This tool is inexpensive, easy to use, and enables users to replace a stem seal in less than a minute.

By compressing the outer sealing lip and expanding the inner lip, the kit makes it easy to slip the “U” cup stem seal over the valve stem. Once the stem seal is properly installed on the valve stem, it can be easily inserted into the bonnet gland and secured without damaging the critical edges of the seal.

A CPV Replacement Soft Goods Kit can also be ordered in the pipe size and soft goods material specified for the user’s application. This kit contains one of each: stem seal, body O-ring, back-up ring, and seat O-ring.

CPV has been a leading manufacturer of valves and fittings since 1915. The company’s innovative designs are well suited to standard applications, as well as one-of-akind custom requirements.
