Degreased Male Threaded Couplings

CPX Copper Threaded Coupling is a durable and corrosion-resistant material that is commonly used in medical applications due to its excellent electrical conductivity and biocompatibility. The couplings are threaded on both ends, allowing them to be easily connected to other components or devices. Manufactured in the UK under BS EN 13485 Medical Devices: Quality Management Systems, exclusively designed for medical gas systems (MGPS).

CPX Copper Threaded Couplings are made of high-quality copper, which is known for its excellent thermal and electrical conductivity as well as its resistance to corrosion. This makes copper an ideal material for medical applications, as it can ensure the safe and efficient transfer of fluids and gases.

More Information

Our degreased slip copper couplings typically feature a smooth, polished surface to prevent any obstruction or buildup of debris that can compromise the sterility of the medical equipment.

Overall, copper straight couplings for medical use are reliable, durable, and safe devices that play an essential role in ensuring the proper functioning of medical equipment and the delivery of necessary fluids and gases in various medical procedures. They are suitable for jointing degreased medical gas copper tube pipelines compliant with BS EN 13348, BS EN 1057, and BS 2871 Part 1 Table X as quoted in HTM 02-01 and C11.
