RLS 19kN 8-Jaw Set

A Complete Range of Jaws for Every Press

Pair this 8-jaw kit with the RLS 19kN Press Tool to create a full, ready-to-go setup for pressing copper tubing up to 1-3/8″. This comprehensive set includes the most commonly used sizes: 1/4″, 3/8″, 1/2″, 5/8″, 3/4″, 7/8, 1-1/8″, and 1-3/8″—giving HVAC/R pros the versatility to handle everything from residential service calls to light commercial installs.

Each RLS jaw is built for precision and performance and presses a distinct RLS witness mark into every fitting—giving you visual assurance that every joint is fully and properly pressed. Engineered for durability and speed, these jaws help deliver clean, consistent connections without flame, fire watch, or flux.
