1/4" SAE Brass Cap - CPS Products

The CPS Products AVC4 1/4" SAE Brass Cap is an essential component engineered for professional automotive and industrial technicians, designed to maintain the integrity of refrigerant systems. This robust, professional-grade service port cap provides a crucial secondary seal, effectively preventing refrigerant loss and protecting delicate service valves from environmental contaminants in various demanding applications. It ensures optimal system efficiency and longevity in demanding service environments.

Key Features

• Durable Brass Construction: Machined from high-quality brass, this cap offers exceptional corrosion resistance and extended service life, even in harsh workshop and field conditions.
• Standard 1/4" SAE Compatibility: Designed for precise fitment, it threads directly onto common 1/4" SAE service ports found on most automotive A/C systems and a wide range of HVAC/R equipment.
• Secure, Leak-Resistant Seal: Works in conjunction with the Schrader valve to provide a reliable seal, safeguarding against refrigerant leakage and helping maintain proper system charge over time.
• Contaminant Protection: Shields delicate service valves from damaging moisture, dust, and debris that can lead to corrosion, blockages, or premature component failure.

Applications

• Automotive A/C Systems: Essential for capping low and high-side 1/4" SAE service ports on passenger vehicles, light trucks, and older R-12/R-134a configurations where 1/4" fittings are utilized.
• HVAC/R Service: Ideal for sealing access fittings on commercial and residential air conditioning units, heat pumps, and various refrigeration equipment.
• Industrial Refrigeration: Protecting ports on chiller plants, walk-in coolers, display cases, and other process cooling systems in industrial and commercial settings.
• General Fluid and Gas Handling: Suitable for capping unused or temporary 1/4" SAE ports in compatible fluid transfer, vacuum, and test setups requiring a reliable mechanical seal.
