Compression coupler PHANTEKS PH-STC1310_CR, brass, inner diameter 13 mm, 1 pc

PHANTEKS Compression coupler PH-STC1310_CR is a brass compression fitting with an inner diameter of 13 mm supplied as a single piece. Engineered for compression connections in liquid cooling and plumbing loops, this coupler creates a metal-to-metal seal compatible with rigid or flexible tubing. Manufactured from CNC-machined solid brass and finished with corrosion-resistant plating, the coupling is intended for assembly, repair, or modification of coolant lines and compact plumbing systems where a durable, low-profile joint is required.

Advantages

The brass construction provides mechanical strength and thermal stability while maintaining precise dimensional tolerances for predictable compression sealing. CNC machining ensures a consistent high-flow internal profile that minimizes restriction in coolant circuits. The fitting uses durable elastomer sealing materials derived from automotive and aerospace applications to deliver long-term reliability. Its single-piece design simplifies installation and reduces potential leak points compared with multi-part connectors.

Suitable for

• Custom PC liquid cooling loops using 13 mm inner-diameter tubing
• Repairing or extending coolant lines in compact cooling systems
• Small-scale plumbing applications requiring a metal compression connection
• Situations where a compact, robust brass coupler is needed

Key specifications

• Material: CNC-machined solid brass
• Finish: corrosion-resistant plating (mirror chrome option available)
• Inner diameter: 13 mm
• Seal type: elastomeric compression seal optimized for durability
• Quantity: single piece

How to use

Prepare tubing ends by cutting square and deburring to ensure a proper seal. Slide the tubing into the coupler until it seats fully against the internal stop, then secure the compression mechanism according to the tubing type and manufacturer recommendations. Verify alignment and hand-tighten until the compression seal engages; if applicable, follow torque guidance for final tightening to avoid over-compression. After installation, pressure-test the loop with coolant to confirm a secure, leak-free connection before returning the system to normal operation.

Recommendations

Use compatible 13 mm inner-diameter tubing and ensure tubing wall thickness matches the compression design. Avoid excessive torque when tightening to prevent deformation of the tubing or fitting; perform a controlled pressure test after assembly. For long-term installations, check seals periodically and replace elastomer components if signs of wear or hardening appear.
