Dry Disconnect Couplings

Dry Disconnect Couplings are the given choice for handling any liquid, chemicals, gas.

The standardized interface to STANAG 3756 with its bayonet coupling principle has been widely accepted in the industry. Application for industrial process plant, road and rail tankers, IBC containers, pharmaceutical and petrochemical industries etc.

Size from:	1” to 8”
Material:	Aluminium, Brass, Stainless Steel, Hastelloy, Titanium, PVDF, PEEK etc.
Seals:	•FKM, NBR, EPDM, FFKM etc.
Working pressure	10-25 Bars (five times safety factor).

Available with threaded and flanged connections, for both hose unit and tank unit.
