Alphacool Apex Grip predlžovací adaptér 20 mm G1/4 vonkajší na vnútorný závit chróm (14898)

Double O-ring sealed brass extension with chrome finish – 20mm reach for tight G1/4" ports.

Overview

The Alphacool Apex Grip Extension 20mm AG/IG G1/4 chrome is a precision-machined brass fitting engineered to add 20mm of clearance between G1/4" threaded components in custom water cooling loops. Its male-to-female configuration (AG/IG) screws directly into any standard G1/4" female port and provides a female G1/4" port on the opposite end, allowing radiators, reservoirs, CPU blocks, or GPU blocks to be spaced further apart. This is particularly useful when fittings collide with nearby components or when tubing runs require a straighter path. The extension is part of the Alphacool Apex Grip series, known for its knurled gripping surface that simplifies hand-tightening even in cramped spaces.

What stands out

• 20mm extension length – resolves clearance issues without bulky adapters.
• Double EPDM O-ring seal – redundant leak protection for long-term reliability.
• Chrome-plated brass body – excellent corrosion resistance and a mirror-like finish.
• Knurled grip pattern – secure finger-tightening; no tools required in most builds.
• Fixed (non-rotary) design – maintains exact orientation once installed.
