6PCS Service Access Valves, Reliable Brass and Copper Core, Strong Sealing AC Charging Port, Universal Fit for Refrigeration Systems (3 Size)

Feature: 【Reliable Material】The service access valve is made of solid brass and copper, making it sturdy and reliable, which helps withstand the pressure and vibrations in refrigeration systems. The overall structure is thoughtfully designed to provide a stable and reliable interface solution for refrigerant pipeline connections.【Wide Application】This AC access valve is suitable for the installation and maintenance of various refrigeration systems, demonstrating good adaptability, especially during refrigerant charging and system debugging. Its design takes into account the usage conditions of common air conditioning models, allowing it to function effectively in multiple refrigerant flow scenarios, thereby facilitating efficient control and transmission of the system medium.【Smooth Control】The valve stem is an independent valve that, when opened, introduces gas into the chamber, helping to reduce turbulence and pressure fluctuations. This design considers the stability of system control, aiming to achieve smooth regulation of medium flow, which may positively impact the overall operational efficiency of the system.【Anti-Slip Clutch Nut】The clutch nut features a deeply knurled texture on its surface. This design significantly increases the friction of the contact surface, allowing installers to perform initial tightening and final locking operations quickly with their fingers in most cases, without the need for specific tools. This simplifies the installation process to some extent and may reduce surface damage to components caused by improper tool use.【Multiple Specifications】To meet the installation requirements of different application scenarios, we offer three specifications of maintenance access valves: regular length, extended length, and thickened version. Each specification package includes two identical maintenance access valves, considering the common practice of using them in pairs during actual maintenance and installation, aiming to help you complete the job in one go and reduce delays caused by missing components.Specification:Name: Service Access ValveModel: Regular Length, Extended Length, Thickened VersionMaterial: CopperLength:Regular Length - 6cm / 2.36inExtended Length - 12.5cm / 4.92inThickened Version - 11.5cm / 4.53inPackage Included:6 * Service Access Valves
