Frequently Asked Questions

What is the GRUVLOK 408EW2 clamp coupling used for?

The GRUVLOK 408EW2 is a rigid grooved pipe coupling for joining 10 in x 10 in pipe in industrial fire protection, HVAC, and process piping systems. Its 316 stainless steel construction and 750 psi rating suit high-pressure, corrosive environments where a rigid, leak-free connection is required.

What are the specifications of the GRUVLOK 408EW2 coupling?

The GRUVLOK 408EW2 is a 316 stainless steel clamp coupling for 10 in x 10 in pipe, with a bolted design and EPDM gasket. It measures 16 25/64 in in length, has a maximum operating pressure of 750 psi, and is classified as rigid (no movement tolerance). MPN 0390065318.

Where to buy the GRUVLOK 408EW2 coupling worldwide?

3G Electric supplies the GRUVLOK 408EW2 coupling to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this rigid grooved pipe coupling.

How to install a GRUVLOK rigid grooved pipe coupling?

Installation requires clean, properly grooved pipe ends per GRUVLOK specifications. Lubricate the EPDM gasket, place it over both pipe ends, then position the coupling housing over the gasket. Tighten bolts evenly to the recommended torque—typically 60-80 ft-lb for 10 in couplings—to achieve a rigid, leak-proof joint.
