Precision 45° Hard-Tube Fitting

The Alphacool Eiszapfen 17407 is a 45-degree rotatable compression fitting designed for 13 mm outer-diameter hard tubing. Its deep black finish resists chipping and matches high-end custom loops. Builders creating tight, angled runs in premium water-cooling systems will appreciate the secure knurled union nut.

G1/4 Thread Integration

The G1/4 thread mates with 95 % of water-blocks, radiators, reservoirs and pumps, so the fitting drops into almost any existing loop without adapters. The rotatable base lets you align the 45° bend after threading, freeing tubing from sharp kinks and reducing stress on acrylic or brass tubes during assembly and transport.

Sustained Seal Reliability

The slanted corners on the union nut press the O-ring evenly against the tube wall, maintaining a leak-free seal through repeated thermal cycles and vibration. The bonded coating survives prolonged coolant contact without degrading, so the fitting keeps its colour and sealing performance over the life of the loop.

Questions about this item

Will the 13 mm hard tube stay sealed under continuous pump pressure?

The slanted corners on the union nut press the O-ring firmly against the tube for a secure hold that resists vibration and transport shock.

Does the Deep Black coating chip when the fitting runs warm all day?

A special surface procedure binds the coating firmly, preventing chipping or peeling even after prolonged operation.

My blocks use G1/4 threads — does this 45° rotatable fitting connect directly?

Yes, the G1/4 threaded side fits 95 % of water-cooling components and rotates freely for easy alignment.
