RLS XL Collar Jaws – 2-1/8″

XL Collar Jaws for Large-Diameter Presses 2 ⅛”

When the job calls for large diameter pipe, RLS has your back. Our XL Collar Jaws are the only flame-free solution in the industry for pressing 2-1/8″ copper tube—saving time, boosting safety, and eliminating the headaches of brazing large-diameter lines.

Built for use with the Klauke 32kN Long-Throw Press Tool and our 32kN Actuator Jaw, this collar system forms secure, permanent joints in just 25 seconds. No flame, no nitrogen purge, and no hot work permits—just fast, clean connections that stand up to pressure, vibration, and thermal cycling.

Each collar jaw set includes an XL press gauge and depth gauge to ensure every connection is properly prepped and fully pressed. And like all RLS jaws, the XL system imprints our RLS witness mark into every fitting—your visual check that the job’s been done right.

RLS XL fittings are designed for large-scale HVAC/R systems commonly found in cold storage facilities, data centers, food and beverage plants, supermarkets, hospitals, and other commercial or industrial buildings where high-capacity refrigerant lines—like 2-1/8″—are essential for reliable cooling performance.
