Frequently Asked Questions

What is a GRUVLOK rigid bolted clamp coupling used for?

A GRUVLOK rigid bolted clamp coupling, like the 408EX3 model, is used to join grooved-end pipes in industrial piping systems. It provides a rigid, leak-tight connection for applications such as fire protection, HVAC, and process piping, handling pressures up to 300 psi.

What are the specifications of the GRUVLOK 408EX3 coupling?

The GRUVLOK 408EX3 is a rigid bolted grooved pipe coupling for 2 in x 2 in pipe. It is made of ductile iron with an NBR seal and has a maximum operating pressure of 300 psi. The manufacturer part number is 0390212710.

Where to buy GRUVLOK couplings in worldwide?

3G Electric supplies GRUVLOK couplings, including the 408EX3 model, to customers worldwide. We handle full logistics and customs clearance to deliver industrial piping components globally. Contact us for pricing and lead time on your order.

How to install a GRUVLOK rigid coupling?

To install a GRUVLOK rigid coupling, ensure pipe ends are clean and grooved per manufacturer specs. Lubricate the NBR gasket, place it over one pipe end, then slide the coupling housing over the gasket. Insert bolts and tighten evenly to the recommended torque for a leak-free joint.
