T Fitting with Valve Core 1/4" SAE T-Type Service Charging Adapter (Female - Male - Valve Core Outlet)

Allowing safe and practical access to the system's pressurized line during maintenance, repair or refrigerant charging of air conditioning and refrigeration systems, the T Fitting with Valve Core (T-Type Service Charging Adapter) is one of the fittings professionals in the field need most. It integrates easily into the existing line and adds an extra service port.

Uninterrupted Line and Practical Charging with the Three-Way Design

This special T fitting creates an extra connection point without altering the system's existing layout. While the knurled female side (nut face) connects directly to the air conditioner's existing service port, the male threaded end allows the system's standard pipeline to continue. The capped Schrader valve outlet in the middle lets you take instant pressure readings or charge refrigerant without losing gas, even while the system is pressurized.

Key Technical Specifications and Equipment

Designed to withstand the harsh conditions of high-pressure refrigeration systems, this brass T fitting's details are as follows:

• Product Type: T Fitting with Valve Core (T-Type Service Valve Adapter)
• Connection Sizes: 1/4" SAE Female (Knurled Nut) x 1/4" SAE Male x 1/4" SAE Valve Core Outlet
• Material: Heavy-duty brass body resistant to corrosion, rust and high pressure.
• Valve Core Mechanism: Integrated Schrader valve (pin-type valve core) that allows a manifold hose to be attached without venting gas, and a knurled protective brass cap.
• Application: Air conditioners, refrigeration systems, heat pumps and HVAC lines requiring an extra service port.

Practical Usage Note for Field Technicians

Technician's Note: This T fitting is a lifesaver when you want to add an extra measuring or charging point to the system. To add a charging or vacuum port without cutting the existing line, connect the female fitting to the unit and continue the line from the male side. When you attach the manifold hose to the valve core outlet in the middle, the pin is pushed in and the line opens; when you remove the hose, the valve core closes automatically and stops gas leakage instantly. Its own cap also provides long-term complete sealing.
