Computer cooling part BitsPower BP-MBCPF-CC4 brass black, dimensions 22×22×26.7 mm

BitsPower BP-MBCPF-CC4 brass black is a compact computer cooling part designed for custom liquid cooling loops. Made of high-quality brass with a deep black electroplated finish, this component measures 22 × 22 × 26.7 mm and is intended for use where a small, durable fitting or adapter is required. The design incorporates a hidden O-ring and a true hi-flow profile to maintain efficient coolant circulation while minimizing flow restriction. It is RoHS compliant and specifically engineered as a compression-style fitting compatible with Tygon 3603 tubing (ID 1/2", OD 5/8", wall 1/16").

Advantages

The brass construction provides strength and corrosion resistance for long-term use in PC water-cooling systems, while the e-plated deep black surface offers visual consistency with black-themed builds and additional protection against wear. The hidden O-ring design reduces exposed sealing elements, improving aesthetics and reducing the chance of accidental damage. The true hi-flow internal geometry supports efficient coolant movement, and the compact dimensions allow placement in tight spaces where larger fittings would not fit.

Suitable for

• Custom PC liquid cooling loops requiring small fittings or adapters
• Connections with Tygon 3603 tubing (ID 1/2", OD 5/8", wall 1/16")
• Compact builds and tight mounting locations inside cases
• Systems where matching black hardware and durable brass components are desired

Key specifications

• Compliance: RoHS

How to use

Install the BitsPower BP-MBCPF-CC4 by sliding the compatible Tygon 3603 tubing onto the fitting until it seats against the internal stop. Tighten the compression portion according to the fitting type to compress the hidden O-ring and create a secure, leak-resistant seal. Ensure mating surfaces of blocks or other fittings are clean and free of debris before assembly. After installation, perform a pressure or leak test on the cooling loop following standard PC water-cooling safety procedures before powering the system.

Recommendations

Use this fitting specifically with tubing that matches the stated inner and outer diameters (Tygon 3603 ID 1/2" OD 5/8") to ensure proper sealing and avoid leaks. During installation, hand-tighten and then apply the recommended additional torque specified by the compression fitting manufacturer; avoid over-tightening to prevent damage to the tubing or threads. Periodically inspect connections for signs of wear or corrosion and replace O-rings if leaks are detected.
