High-End Hard-Tube Fitting

The Alphacool Eiszapfen 1011192 is a G1/4-inch compression fitting designed for 13mm outer-diameter rigid tubing. Its knurled nut allows secure hand-tightening without tools. The chrome coating is bonded through a special process that resists chipping and peeling over time. This single fitting suits custom-loop builders who prioritise durability and a consistent metallic finish.

Replaces Standard Compression Fittings

The slanted corners on the connecting nut press the included O-ring more firmly against the tube wall than conventional designs. This upgrade is worth it when vibration during transport or long-term thermal cycling risk loosening lesser fittings. Three coloured O-rings are supplied, letting you match or contrast the loop aesthetic without buying separate kits. The high-flow internal profile adds no restriction compared to basic couplings.

Integrates Into G1/4 Threaded Components

One end screws into any component with a G1/4 female port such as radiators, blocks, reservoirs or pumps. The other end accepts 13mm hard tubes made of acrylic, PETG, brass or similar rigid materials. No proprietary tools or adhesives are required, freeing layout changes and future maintenance. The knurled grip also eases disassembly in tight chassis corners where spanner access is limited.

Questions about this item

What size hard tube fits the 13 mm compression end?

The compression end accepts rigid tubes with a 13 mm outer diameter.

How do I install the G1/4" thread without damaging the O-ring?

Screw the knurled nut into the G1/4" port by hand until the O-ring seats, then give a light quarter-turn with fingers — avoid tools that can overtighten and pinch the ring.

When should I replace the coloured O-rings supplied with the fitting?

Replace the O-rings if they show flattening, cracking or loss of elasticity after disassembly, or whenever you rebuild the loop.
