Carrier ACPTP2 Geothermal Pressure Temperature Plug

Product Description

The CARRIER ACPTP2 is a pressure and temperature plug designed for use in geothermal heating and cooling systems. It fits a 1/2 inch male pipe thread (MPT) port and provides a sealed access point for monitoring loop pressure and fluid temperature during system commissioning and service. Licensed HVAC technicians and geothermal system installers use this plug to maintain loop integrity while allowing periodic test-point access without introducing leaks or air into the closed loop.

This plug is suited for residential and light commercial geothermal installations where ground-loop or water-loop systems require routine pressure and temperature monitoring. It is installed at designated test ports on the system piping, typically near the heat pump unit or at manifold stations. The 1/2 inch MPT thread size is a common port size on geothermal loop piping and distribution manifolds.

Key Features

• 1/2 inch MPT connection fits standard geothermal loop test ports
• Provides sealed access for pressure and temperature readings
• Supports system commissioning and routine service diagnostics
• OEM part for CARRIER geothermal systems

Compatibility

Designed as an OEM-style replacement pressure and temperature plug for CARRIER geothermal heat pump systems with 1/2 inch MPT test port fittings.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with closed-loop geothermal systems. Shut down the heat pump and relieve loop pressure before removing or installing any test-point plug. Use appropriate thread sealant rated for the loop fluid in use. Follow applicable mechanical and plumbing codes when servicing geothermal loop piping.
