Request Information
The 84 Series coupling is a cartridge mount coupling used primarily for subsea tree control systems. Testing has shown that up to 500 connect/disconnect cycles can be performed without damage to the metal seal. The highly reliable 84 Series coupling has been extensively tested, with thousands currently in use today.
