Copeland 510-0191-00 Schrader Tee Valve

The Copeland 510-0191-00 Schrader Tee Valve is a brass Schrader access tee that gives you a service port on a Copeland compressor’s oil pressure connection. It is a brass tee with a flare fitting on one end, a male pipe thread on the other, and a knurled Schrader cap on the branch, so you can hook a gauge to the port without breaking into the line. Distributors list the 510-0191-00 as the 1/4" oil pressure access valve for the oil pump housing on Copeland compressors.

This is the fitting you use when you need to check oil pressure against suction pressure to see what the compressor’s oil pump is really doing. The Schrader valve core is spring-loaded and self-sealing, so a gauge hose can be threaded on and taken off without losing refrigerant or oil, and the knurled cap is the secondary seal that keeps the port leak-tight between visits. If a cap goes missing or the core starts to weep, a Schrader tee like the 510-0191-00 is a faster, cleaner fix than a temporary plug. Confirm the flare and pipe thread ends against the fitting you are replacing.

Key Benefits

• Gauge Access Without Opening the System: The Schrader core seals when the hose comes off, so you can read oil pressure repeatedly.
• All-Brass Construction: A brass tee with flare and male pipe thread ends that stands up to compressor vibration.
• Cap Included: The knurled brass cap is the secondary seal that protects the core from leaks and dirt.
• OEM Copeland Part: The 510-0191-00 is the same access valve the factory uses on the oil pump housing.

Common Questions

• What is this used for? It provides a Schrader service port for reading oil pressure on Copeland compressors that use an oil pump.
• Can I replace just the Schrader core? The core is serviceable, but if the tee body, threads, or cap are damaged, replace the whole 510-0191-00 tee.
• How do I verify it is the right fitting? Match the flare end and male pipe thread to the valve on your compressor, and check the Copeland parts list for your model and serial number.
