Faster, Safer, and Smarter Solution

Offering connections in seconds and providing performance for years, the GRINNELL G-PRESS Copper System is one of the fastest, safest, and smartest pipe-joining solutions available.

In a matter of seconds, G-PRESS Piping Systems can be installed to fit tight time constraints and budgets. Additionally, the Leak-Before-Press feature quickly identifies any installed fittings that have not been properly pressed.

Connections with G-PRESS Copper Fittings create durable, air- and water-tight seals with an easy-to-use crimping tool, eliminating all soldering or welding. G-PRESS fittings also eliminate fumes, flames and cutting oils, creating a cleaner, safer work environment.

Flexible and Complete Product Offering

For greater versatility, a full line of G-PRESS Copper Fittings are available in ½-inch (12.7mm) through 2-inch (50mm) sizes. For tube sizes larger than 2-inches (50mm), G-PRESS fittings allow a transition to GRINNELL Grooved Copper Fittings. GRINNELL Grooved Copper Fittings are available in 2-inch through 8-inch (50mm - 200mm) sizes. These mechanically joined press fittings are designed to work with hard (drawn tempered), half-hard, and soft (annealed) copper tubes.

Easy Installation

A G-PRESS Copper System is the ideal solution for a variety of applications such as hot and cold potable water systems, hydronic systems, and process piping. G-PRESS Copper Fittings are available in copper and lead-free brass.
