Description
This ABS composite union combines a solvent weld female socket with a durable brass female BSP threaded insert, providing a secure and serviceable transition within an ABS pipeline. The plain end is bonded to ABS pipe or fittings using solvent cement and cleaner, forming a strong and permanent joint. The brass threaded side offers excellent mechanical strength, making it suitable for connecting metal valves, pumps, gauges and other threaded components where repeated assembly or disassembly may be required. The union design allows the line to be opened without cutting the pipe, supporting easy maintenance access. Manufactured from high quality ABS with a precision brass insert, this fitting delivers long lasting performance across industrial, commercial and process environments.
