Guillemin Type Couplings

Guillemin type couplings are widely used on tankers for bulk powder and granule transfer. The units have an identical locking head with no separate male or female half. They are available with or without locking rings. The hose tail units are offered with a standard serrated tail for fitting onto rubber hose, with a 'scroll' tail available for fitting onto composite hose. Two units with a locking ring can be safely connected as can one unit with a locking ring and one without.
