Cooling system part BitsPower BP-BSCPF-CC3U metal fitting, brass/nickel, 1/4 inch thread

BitsPower BP-BSCPF-CC3U metal fitting, brass with nickel plating, is a compression-style component for PC liquid cooling loops. It accepts a 1/4" thread and is designed to secure soft tubing with an inner diameter of 3/8" and outer diameter of 5/8". The fitting connects radiators, water blocks, pumps and reservoirs with a metal-to-metal body and plated finish that resists corrosion while providing a stable, leak-resistant joint when used with compatible tubing and compression rings.

Advantages

The brass construction combined with nickel plating improves mechanical strength and corrosion resistance compared with unplated materials. The 1/4" threaded connection is compatible with common compression fittings and standard threaded ports found on many radiators and water-cooling components. The compression design secures tubing without the need for additional clamps, and the smooth plated surface minimizes wear on tubing during installation and operation.

Suitable for

• Custom PC water-cooling loops using soft tubing with ID 3/8" and OD 5/8"
• Connecting radiators, CPU/GPU water blocks, pumps and reservoirs
• Replacement or upgrade of existing compression fittings with 1/4" thread

Key specifications

• Material: brass with nickel plating
• Thread size: 1/4" (standard G1/4 compatible)
• Tube compatibility: inner diameter 3/8", outer diameter 5/8"
• Type: compression-style metal fitting
• Finish: nickel-plated smooth surface

How to use

Ensure the fitting and the mating port are clean and free of debris. Slide the compression ring and any supplied ferrule onto the tubing, insert the tubing fully into the fitting body until it seats, then thread the fitting into the component port by hand to avoid cross-threading. Tighten to a firm hand/half-turn with an appropriate wrench if specified by your cooling component manufacturer; avoid over-tightening to prevent damage to threads or tubing. After installation, perform a leak test at low pressure or by running the loop with distilled water to verify seals before full operation.

Recommendations

Use compatible soft tubing (ID 3/8" / OD 5/8") and the correct compression ring or ferrule supplied with compression fittings. When combining fittings and components, verify that all threaded connections use the same standard (1/4") and inspect seals during initial testing to ensure reliable, long-term leak-free performance.
