G1/4-inch Sealing O-rings 50 pcs, XSPC — black

Pack of 50 black G1/4-inch sealing O-rings from XSPC designed for use with G1/4 threaded fittings. These rubber O-rings create a compression seal between mating surfaces to prevent leaks in water-cooling loops, plumbing connections, and pneumatic fittings that use G1/4 threads. Supplied in a uniform size and material, the set is intended for maintenance, replacing worn seals, or equipping new assemblies where multiple consistent gaskets are required.

Advantages

These O-rings are supplied in a bulk pack of 50, providing a convenient quantity for multiple fittings or future replacements. The uniform black rubber construction offers consistent elasticity and compressibility to form reliable seals under standard operating pressures for typical G1/4 applications. The rings are sized to match G1/4 threaded components, helping reduce the need for on-the-spot measurement and ensuring interchangeability across compatible fittings.

Suitable for

• Sealing G1/4 threaded water-cooling fittings and compression fittings
• Replacement of worn or damaged O-rings in plumbing or coolant loops
• Assembly of new builds requiring multiple identical gaskets
• Light pneumatic connections that accept G1/4 seals

Key specifications

• Quantity: 50 pieces per pack
• Color: Black
• Compatible thread type: G1/4 (intended for G1/4 threaded fittings)
• Material type: Rubber elastomer (standard sealing compound for general-purpose fittings)
• Application: Sealing for liquid and compatible low-pressure gas connections

How to use

Select the correct O-ring from the pack and place it into the groove or threaded junction of the G1/4 fitting. Ensure contact surfaces are clean and free of debris or old sealant before installation. Hand-tighten the fitting to compress the O-ring and, if required, complete final tightening with the appropriate tool to the manufacturer’s torque specification for the mating component. After installation, inspect the joint under operating conditions for any signs of seepage and re-check tightness after a short run period.

Recommendations

Store unused O-rings in a cool, dry place away from direct sunlight and ozone sources to preserve elasticity. For long-term reliability, replace O-rings showing cracks, hardening, or permanent deformation. When working with aggressive chemicals, high temperatures, or high-pressure systems, verify material compatibility and consider using seals specified for those conditions rather than general-purpose rubber O-rings.
