Overview

A minimalist straight compression fitting that connects 12mm acrylic or PETG tubing to a G1/4 female port. The satin silver brass body has no external branding and accepts optional colored accent rings.

Design and Materials

The fitting body and compression ring are CNC machined from brass with a high-quality satin silver finish. The interior is left unpainted to minimize potential contaminants in the coolant loop. No logos or branding appear on the exterior surfaces.

Installation and Security

A locking ring compresses the rubber O-ring to prevent the tube from pulling out. External grooves aid hand tightening, while a 9mm hex socket inside the barb allows Allen key installation to protect fingertips. Excessive torque should be avoided to prevent damage to other components.

Compatibility and Options

Designed for 12mm outer diameter solid tubing including acrylic, PETG, copper, brass, and stainless steel. Interchangeable aesthetic color rings thread onto the fitting before the locking ring and are sold separately. Guaranteed compatible with all EK Water Blocks liquid cooling products.
