## Description

A dedicated stop valve helps connect indoor and outdoor sections of a split air conditioner while giving access to open or close the refrigerant circuit. This PATIKIL fitting is designed for 3/8-inch outside-diameter copper tube, making it a practical component for compatible mini-split air-conditioning and refrigeration service work.

Its brass construction and flare connection support a focused repair or maintenance task. Use it where a service valve is needed to connect copper piping and manage the refrigerant circuit.

## Tech summary
This straight, three-way angle stop service valve is made of brass and has a brass-tone finish. The flare nut is designed to help connect copper pipe, while the valve can be used to open or close the refrigerant circuit. For service work, it also supports vacuuming or filling the circuit. Its compact fitting format provides a specific connection point rather than serving as a general-purpose pipe connector.

## What it works with
The fitting is intended for 3/8-inch outside-diameter copper pipe and is used in split air-conditioning systems to connect the outdoor unit with the indoor unit. It is also described for air-conditioning and refrigeration equipment, HVAC systems, plumbing hardware, hot and cold water supply equipment, and air-energy water heaters. Match the copper tube size and connection requirements to the system before choosing a fitting, the stated pipe size is the key compatibility detail.

For a repair focused on controlling a refrigerant circuit, a dedicated service valve is a more targeted choice than a general pipe connector. Its flare nut supports the copper-pipe connection, and the valve’s open-and-close function is relevant when servicing the circuit.

## Everyday use
In a compatible mini-split system, the valve provides a connection between the indoor and outdoor sections and can be used to close or open the refrigerant circuit. During air-conditioning maintenance or repair, that function supports tasks such as vacuuming or filling the circuit. The fitting is also applicable to refrigeration equipment, so it can suit service work where the same 3/8-inch OD copper tube size and connection arrangement are required.

The brass fitting is described as sturdy, hard and corrosion-resistant for durable use. For a planned repair, identify the copper pipe’s outside diameter first, then select the valve for that connection and the intended service task. This keeps the choice centred on fit and function instead of relying on a generic connector for a refrigerant line.

## Questions before you buy

**What pipe size does this valve fit?** It is specified for copper pipe with a 3/8-inch outside diameter, also listed as 9.52 mm. Confirm the tube size for the connection where the valve will be used.

**What is the valve used for in a split air conditioner?** It can connect the indoor and outdoor units and open or close the refrigerant circuit. It is also described for vacuuming or filling the circuit during maintenance and repair.

**What material and connection does it use?** The fitting is brass and uses a flare connection with a flare nut for connecting copper pipe. The listed thread type is NPT.

## Should you buy it?
Choose this PATIKIL stop valve when the job calls for a service fitting for 3/8-inch OD copper tube in a compatible air-conditioning or refrigeration setup. Its brass construction, flare connection and circuit-control function make it suited to targeted connection, maintenance and repair work where those specifications match the system.
