Home / Products / Dry Disconnect Couplings

Our company, working to prevent air pollution and protect people and the environment from harmful waste, has conducted R&D to produce safe, eco-friendly products for filtering aggressive liquids in chemical and petrochemical transport, and has started manufacturing Dry Disconnect Couplings — previously imported — using entirely domestic capabilities.

Following approximately five months of R&D, we developed and launched Dry Disconnect Couplings for truck tankers, rail tankers and tank containers transporting chemical substances, petroleum derivatives and LPG, to prevent liquid loss and protect the environment from chemical waste.

Dry Disconnect Couplings manufactured by User Makina comply with European standards and are certified according to ATEX and ADR regulations, and also hold the CE certificate under the European Pressure Equipment Directive (PED).
