Anvil International Gruvlok Coupling with Pre-Installed SLT Fittings
April 3, 2020
Anvil International’s new Gruvlok Coupling with pre-installed SLT Fittings installs five times faster than industry-standard grooved fittings in fire protection systems. The new Figure FP7074SLT and SE5-SLT utilize a patented design to allow caps and end of line fittings to be pre-installed at the factory, eliminating the need for field fabrication. No loose parts and no special tools required means installation is as easy as simply pushing the FP7074SLT or SE5-SLT on the pipe and tightening the nuts.
