The CG-LOK Hose Unit (Flange) Dry Disconnect Coupling is the hose side of a dry break connection finished with a bolted ANSI 150 lbs flange instead of a thread. Flanged ends suit larger bores and higher duty installations, where a bolted joint with a gasket is preferred over a threaded connection for strength, sealing and inspection. It mates with a CG-LOK tank unit and seals on both sides before parting, so no product is lost at disconnection.
Key Features
• Hose side (TH) unit with operating handles and ANSI 150 lbs flange connection
• Bolted flanged joint suited to larger bores and higher duty transfer systems
• Bidirectional sealing prevents product loss and vapour release on disconnection
• Sizes 1″, 2″, 2½”, 3″, 4″, 6″ and 8″, with other flange types available on request
• Stainless steel 1.4408, aluminium or brass bodies, ATEX and PED certified

How It Works
Operation is a two stage turn that keeps the valves shut until the connection is secure. Turning the hose unit 15 degrees clockwise locks the two units together while both valves stay closed. Turning a further 90 degrees opens the internal valves and allows flow. Reversing the sequence closes the valves before the units separate, so product is contained on both sides at the moment of disconnection.
Applications
Marine and barge transfer, terminal loading arms, large bore chemical and petroleum lines, and fixed transfer systems at refineries, tank farms and jetties across Pasir Gudang, Port Klang, Kerteh, Kemaman, Bintulu and Labuan.

Frequently Asked Questions
When should I choose a flanged unit over a threaded one?
Flanged connections suit larger bores, higher duty service and fixed installations where a bolted gasketed joint is preferred for strength and ease of inspection. Threaded units suit smaller bores and more mobile setups.
Are other flange standards available?
The standard offering is ANSI 150 lbs. Other flange types and drilling standards can be supplied on request, so give Flytech your piping specification and it will be matched.
Is this coupling suitable for hazardous areas?
CG-LOK dry disconnect couplings carry ATEX certification along with PED 2014/68/EU, and a 3.1 material certificate can be supplied. Confirm your specific zone classification when ordering.
