Alphacool Eiszapfen 14mm HardTube Fitting

This Alphacool Eiszapfen compression fitting connects 14mm outer-diameter hard tubing to any component with a G1/4 thread. It suits custom-loop builders who want a secure, leak-free joint finished in Deep Black. The knurled union nut allows firm hand-tightening without tools. The fitting is sold individually as part number 1019796.

Triple O-ring sealing system

The decisive specification is the triple O-ring seal that locks the tube inside the fitting. Two rings sit inside the body while a third compresses under the union nut, creating a redundant barrier and increasing tube retention force. This design targets builders who prioritise long-term reliability over quick-disconnect convenience. No other sealing method is used on this model.

Hand-tight installation with deburred tube

Assembly requires removing the union nut and inner O-ring, threading the body into the G1/4 port, then inserting a cleanly deburred hard tube before tightening the nut by hand. The most common error is skipping the deburring step, which can damage an O-ring and cause a slow leak. The laser-etched logo resists wear during repeated disassembly.

商品問答

Will the 14 mm hard tube sit flush and seal reliably once the fitting is tightened in a loop?

The triple sealing system uses two internal O-rings plus a third that compresses against the tube when the union nut is tightened, giving a secure seal and strong pull-out resistance.

What thread standard does the G1/4 connection follow, and which components will it screw into?

It uses the standard G1/4 inch parallel thread found on most water-blocks, radiators, reservoirs and pumps, so it fits any component with that port.

How much clearance does the knurled union nut need to tighten by hand around the 14 mm tube?

The knurled nut is designed for finger tightening on 14 mm OD hard tube; allow enough space around the port for a comfortable grip to compress the O-ring fully.
