Brass Service Port Cap for Air Conditioning Compressor

A/C Service Port Caps (High & Low Side)

Protect your air conditioning system with these service port caps, designed to seal the high and low pressure ports on the A/C compressor.

More than just dust covers, these caps act as a secondary seal to the Schrader valve, helping to prevent slow refrigerant leaks and maintain proper system pressure over time.

They also keep dirt, moisture, and debris out of the service ports—protecting the valve core and ensuring long-term reliability of your A/C system.

Features:

• Fits standard A/C service ports (high & low side)
• Provides a secondary seal to help prevent leaks
• Keeps out dust, moisture, and contaminants
• Helps extend service life of the A/C system
• Simple but essential for proper system maintenance

A small part that makes a big difference—don’t overlook it.
