Computer cooling system part BitsPower BP-WTP-C42 — Brass nickel-plated fitting

BitsPower BP-WTP-C42 is a metal fitting for computer liquid-cooling systems, manufactured from high-quality brass with a nickel/silver finish. Designed for use in custom water-cooling loops, this fitting delivers a high-flow path and corrosion-resistant surface to maintain stable coolant circulation and reliable seals. The fitting's construction supports dual G1/4" threaded connections and conceals the O-ring for a clean appearance and protected seal.

Advantages

The brass construction provides strong mechanical durability and thermal stability, while the nickel-plated surface improves corrosion resistance and offers a consistent silver appearance. The true hi-flow internal geometry reduces flow restriction in water-cooling loops. A hidden O-ring design helps protect the seal from debris and simplifies visual integration into a custom build. The part is RoHS compliant and intended for repeated use during upgrades or maintenance.

Suitable for

• Custom PC water-cooling loops requiring durable metal fittings
• Connections between tubing and water blocks, radiators, or pumps
• Maintenance and upgrades of existing liquid-cooling systems
• High-flow cooling layouts where reduced flow resistance is desired

Key specifications

• Material: high-quality brass
• Finish: nickel/silver plated
• Thread type: dual G1/4" compatible connections
• Design: true high-flow internal path
• Seal: concealed O-ring sealing
• Compliance: RoHS compliant

How to use

Install the fitting by threading it into compatible G1/4" ports on water blocks, radiators, or pump housings until hand-tight, then secure with an appropriate wrench if required. Ensure the concealed O-ring seats properly to create a leak-free connection. Use compatible tubing and clamps or compression fittings as needed for your loop configuration. During assembly, avoid overtightening to prevent damage to threads or deformation of the O-ring.

Recommendations

Before filling the loop, perform a pressure or leak test to confirm all connections are sealed. For longevity, periodically inspect fittings for signs of corrosion or seal wear and replace O-rings if aging is observed. Use coolant formulations and maintenance practices recommended for metal components to preserve the nickel finish and brass substrate.
