Frequently Asked Questions

What is a GRUVLOK flex bolted clamp coupling used for?

A GRUVLOK flex bolted clamp coupling joins grooved-end pipes in industrial piping systems, allowing for limited angular movement to accommodate thermal expansion or minor misalignment. It is commonly used in HVAC, fire protection, and process piping where a reliable, leak-tight mechanical joint is required.

What are the specifications of the GRUVLOK 0390003820 coupling?

The GRUVLOK 0390003820 is a 10 in x 10 in flex bolted clamp coupling made of ductile iron with an NBR seal. It has a maximum operating pressure of 800 psi and is designed for grooved pipe connections. This model is supplied by 3G Electric.

Where to buy a GRUVLOK 10 in flex bolted coupling worldwide?

3G Electric supplies the GRUVLOK 10 in flex bolted coupling worldwide, handling full logistics and customs clearance for international orders. As a global industrial solutions provider, we source genuine GRUVLOK parts and deliver them to your site, regardless of location.

How to install a GRUVLOK flex bolted clamp coupling?

To install a GRUVLOK flex bolted clamp coupling, ensure pipe ends are clean and grooved per manufacturer specifications. Place the gasket over the pipe ends, then position the coupling housing over the gasket. Tighten bolts evenly to the recommended torque to achieve a secure, leak-free joint.
