R410A Brass Adapter Kit – 5/16″ to 1/4″ Mini Split Converter

This comprehensive R410A adapter kit from Xhwlgbal provides everything needed for efficient service of mini‑split air‑conditioning and HVAC systems. The set includes two straight swivel adapters, two 45° adapters, two 90° adapters, five thimble pins, five gaskets, five 5V1 spools, and a spool remover, ensuring you have the right component for any installation scenario.

Each adapter is forged from heavy‑duty brass for superior durability under high‑pressure conditions, while the wear‑resistant rubber rings deliver reliable sealing performance. The nut’s deep‑textured outer layer allows quick manual tightening, and the unique thimble design guarantees gas‑tight connections. With three selectable port angles—45°, 90°, and 180°—the kit adapts to tight spaces and complex routing requirements, making it ideal for both new R410A mini‑split units and a wide range of refrigeration equipment.
