Stainless Steel 4″ Union Butt Weld Liner Adapter HB Spec The Stainless Steel 4″ Union Butt Weld Liner Adapter HB Spec is a replacement liner adapter designed for compatible 4″ union pipework used in dairy, milk handling, wash and processing systems. Manufactured from stainless steel, it provides a strong butt weld connection point where a liner adapter is required within the wider pipework assembly. Liner adapters are useful where pipework, vessels or fittings need to connect securely while maintaining a serviceable union arrangement. If the original adapter becomes worn, damaged, distorted, corroded or difficult to seal, the union may not pull together correctly and the system may suffer from leaks, poor alignment or unreliable flow. Replacing it with the Stainless Steel 4″ Union Butt Weld Liner Adapter HB Spec helps restore a dependable pipework connection and supports consistent system performance. This stainless steel adapter is useful for dairy farms, engineers, small producers and service teams carrying out repairs, refurbishment or planned pipework work on compatible 4″ union systems. It is particularly suitable where the surrounding pipework, nut and seal remain serviceable
