Tigbear Service Access Valve Brass 3.54 Stem

Description

Product Overview

The Tigbear Service Access Valve Set is engineered for professional HVAC service and maintenance. Crafted from corrosion‑resistant brass and copper, each valve offers a robust 3.54″ stem and a 1/4″ SAE x 1/4″ OD threaded connection, meeting ASME B16.34 standards for durability under high pressure up to 3200 kPa. The kit includes 20 individually threaded needle valves, each featuring a poppet core assisted by a spring, ensuring precise gas flow control. With a compact 5 × 3 × 1 inch footprint and a lightweight 0.7 lb design, the valves are easy to handle while providing the strength needed for brazing and high‑temperature environments.

Usage

These service access valves are versatile across a range of HVAC applications. Technicians use them to evacuate, charge, and pressure‑test refrigerant lines for systems running R22, R410A, or R134A. The 1/4″ SAE inlet accommodates both flare and compression connections, making the valves compatible with most commercial and residential air‑conditioning units. Ideal for vacuum pump connections, refrigerant recovery, and leak detection, the kit streamlines field service, reducing the need for multiple adapters.
