FASTLOCK CO2 FITTINGS FOR STAINLESS STEEL AND K65 PIPE - CW614N-OT58 BRASS BODY - AISI 316L STAINLESS STEEL NUT - FASTLOCK CO2 CONNECTION - 100% PFAS-FREE OLAB CERTIFIED EPDM O.RING

OLAB FastLock CO2 Series provides a quick, secure, weld-free and 100% PFAS-FREE connection for professional CO2 (R744) refrigeration plants, where flawless sealing is essential. Built around OLAB’s exclusive FastLock CO2 technology, the system delivers a dependable mechanical grip even on non-calibrated pipes, cutting installation time and job-site complexity.

Operation is straightforward: the tube is pushed into the fitting and, as the nut is tightened, a cutting conical ring (BCL) closes onto the tube, locking it mechanically and preventing pull-out. Simultaneously, an internal washer compresses an OLAB-certified, 100% PFAS-FREE EPDM O-Ring into its seat, creating a durable hermetic seal that withstands high pressures and thermal cycling. All of this is achieved without welding, avoiding heat-induced stress on the seals and allowing fast, precise, fully reversible installation—no specialized personnel required.

FastLock CO2 fittings are rated for transcritical service up to 150 bar (2175 psi). The body is machined from OT58 brass (EN12164 – CW614N), while the tightening nut is stainless steel AISI 316, a materials pairing chosen for corrosion resistance, dimensional stability and long-term durability. With its compact form factor, versatile connection options and full compatibility with modern CO2 systems, the FastLock CO2 Series offers a solid, safe and easily integrated 100% PFAS-FREE solution for next-generation refrigeration installations.
