Frequently Asked Questions

What is a GRUVLOK flex bolted clamp coupling used for?

A GRUVLOK flex bolted clamp coupling joins grooved-end pipe in fire protection, HVAC, and industrial piping systems. Its ductile iron body and EPDM seal handle pressures up to 800 psi, allowing for limited angular deflection to accommodate thermal expansion and vibration.

What are the specifications of the GRUVLOK 0390004596 coupling?

The GRUVLOK 0390004596 is a 10 in x 10 in flex bolted clamp coupling made of ductile iron with an EPDM seal. It has a maximum operating pressure of 800 psi and is designed for grooved pipe connections. 3G Electric supplies this OEM part globally.

Where to buy a GRUVLOK 10 in clamp coupling worldwide?

3G Electric sources and delivers the GRUVLOK 10 in flex bolted clamp coupling (MPN 0390004596) to worldwide locations. We handle full logistics and customs clearance as a global industrial supplier, ensuring the correct OEM part reaches your site.

How to install a GRUVLOK flex bolted coupling?

To install a GRUVLOK flex bolted coupling, ensure pipe ends are clean and grooved per manufacturer specs. Place the gasket over the pipe ends, then position the coupling housing over the gasket. Tighten bolts evenly to the recommended torque—do not overtighten. 3G Electric can advise on best practices.
