Product information

Description

Replacement stem seal GG4 from FERRO is designed to restore a watertight seal at the valve stem of radiator and thermostatic valves. This spare seal fits where the original rubber or elastomeric sealing element has worn, hardened or started to leak, allowing quick restoration of valve tightness without replacing the entire valve body. The product is intended for use in central heating systems where compatible dimensions and connection types are present.

Advantages

The GG4 stem seal provides a reliable sealing surface that reduces dripping and water loss in radiator and thermostatic valves. Made from elastomeric material suited for contact with heating fluids, it is compact and easy to handle during servicing. Using a dedicated replacement seal preserves the existing valve assembly and lowers repair cost and downtime compared with full valve replacement.

Suitable for

Repairing leaking radiator valves
Servicing thermostatic radiator valves
Routine maintenance of central heating valve stems
Replacing worn or hardened stem seals in domestic heating systems

Key specifications

Type: stem seal for radiator and thermostatic valves
Material: elastomeric sealing element suitable for heating fluids
Function: provides watertight seal at valve stem to prevent leaks
Form factor: compact replacement seal designed for direct installation in compatible valve stems

How to use

Isolate the heating circuit and drain the section containing the valve to avoid water loss. Disassemble the valve bonnet or actuator following the valve manufacturer's instructions, remove the old sealing element and clean the stem and seat area from deposits. Fit the GG4 replacement seal into the valve in the correct orientation, reassemble the valve components and refill the system. Check for leaks and operate the valve to confirm smooth movement and proper sealing.

Usage recommendations

Verify compatibility of the GG4 seal with the valve model before installation by comparing dimensions and connection type. Use protective gloves when handling system fluids and follow safe draining and refilling procedures for heating systems. If uncertain about compatibility or disassembly, consult a qualified heating engineer.
