Alphacool Apex Grip HardTube compressiefitting 13mm G1/4 - diepzwart, 6-pack 14926

Hard tube compression fittings engineered for secure, leak-free connections in custom PC water cooling loops. The Alphacool Apex Grip series delivers an enhanced grip ring that locks 13mm outer diameter hard tubing firmly in place, even under high pressure and vibration.

Advantages

Each fitting features a double O-ring seal and a precision-machined brass body with a matte black finish. The enhanced grip ring provides superior tube retention compared to standard compression fittings, reducing the risk of accidental disconnection. The straight design fits tight spaces and simplifies tube routing, while the G1/4" thread ensures compatibility with virtually all water cooling components.
