Compression Fitting PHANTEKS PH-STC1310_BK — Brass, Inner Diameter 13 mm, 1 pc.

PHANTEKS PH-STC1310_BK is a single-piece brass compression coupler with a 13 mm inner diameter, engineered for use in liquid cooling and small-scale plumbing loops. CNC-machined from solid brass and finished in satin black, this coupler provides a threaded compression connection that joins two sections of tubing securely. Designed to match Phanteks Glacier Fittings, it emphasizes a high-flow profile and long-term reliability through precision machining and automotive-grade VITON sealing materials.

Advantages

The brass construction offers corrosion resistance and mechanical strength while CNC machining ensures tight dimensional tolerances for consistent, repeatable connections. VITON seals borrowed from automotive and aerospace applications increase chemical and temperature resistance compared with standard elastomers, reducing the risk of leaks over extended operation. The satin black finish provides a uniform appearance that integrates with Phanteks water-cooling components and other system hardware.

Suitable for

• Joining two soft or hard tubing sections with 13 mm inner diameter in PC water-cooling loops
• Small-scale fluid circuits and custom cooling rigs requiring threaded compression joins
• Replacement or expansion of existing Phanteks Glacier Fittings within a cooling loop

Key specifications

• Material: solid brass (CNC-machined)
• Inner diameter: 13 mm
• Finish: satin black
• Sealing material: VITON elastomer
• Package quantity: 1 piece
• Connection type: threaded compression coupler for tubing

How to use

Ensure tubing sections are clean and cut squarely to achieve a proper seal. Slide the compression nut and ferrule components onto each tubing end if applicable, insert tubing ends fully into the coupler, then tighten the threaded compression nut until a firm, leak-free connection is achieved. Do not overtighten; tighten to manufacturer-recommended torque or until the seal compresses without deforming the tubing. After installation, pressurize and inspect the loop for leaks before full operation.

Recommendations

Use compatible tubing with a 13 mm inner diameter and check material compatibility with VITON seals. Avoid exposure to aggressive chemicals not recommended for VITON and perform periodic inspections for tightness and seal condition during extended operation.
