Permasert® Mechanical Couplings
The Permasert coupling has a pull-out strength greater than the connected polyethylene tubing. Its one-piece construction and design ensure consistent, gas-tight connections in all weather conditions. Permasert couplings are non-corrosive and molded from industry leading PE4710/Bimodal PE3408 which provides significant performance advantages versus other polyethylene resins.

PermaLock® Mechanical Tapping Tees
The Elster Perfection PermaLock Mechanical Tapping Tee offers gas line installers a unique combination of speed, economy, and security when connecting a service line to a gas main. PermaLock low profile tapping tees can be installed in as little as five minutes without the need for expensive heat fusion equipment. The simplicity of its installation procedure eliminates the need for extensive training and multiple-person crews. An like all tapping tees, PermaLock tees can be installed without shutting down the main.

Permasert® XL Large Diameter Mechanical Couplings Polyethylene to PE
The couplings feature a center body section constructed of ASTM D-2513/ISO 4437 gas grade polyethylene (3408).To ensure a safe connection, Permasert® XL couplings are designed to withstand the pressure of the PE piping or tubing installed or up to 125 psig for PE-to-steel or cast iron transitions. The Permasert® XL couplings meet or exceed the requirements of US DOT CFR Title 49, Part 192.283(b) and ASTM D-2513 category 1.
