3TL SERIES Transfer Loading Safety Quick Coupling

Innovative sealing technology for the chemical, petrochemical and pharmaceutical industries.

The 3TL Transfer Loading Series is an all-purpose, high-performance quick coupling. Designed with a metal-to-metal wedge seal, the 3TL requires NO HAMMERING for a secure connection regardless of pressure and temperature.

The design offers a non-restrictive flow with no variation in pipe diameter. The reusable metal-to-metal wedge sealing components further enhance the seal as temperature changes are encountered. The retaining ring ensures safe venting of any residual pressure.
