JB K1-8 1/2" NPS x 1/4" Male Flare Drum Adapter

The JB K1-8 1/2" NPS x 1/4" Male Flare Drum Adapter is a critical component for technicians requiring a reliable transition between a refrigerant drum connection and standard service manifolds. Machined from high-grade heavy-duty brass consisting of 65% copper and 35% zinc, this fitting is engineered for high tensile strength and superior corrosion resistance in demanding field environments. This HVAC tank adapter utilizes a 1/2" NPS female thread to mate with domestic refrigerant cylinders, expanding them to a standard 1/4" SAE flare connection. Unlike lower-quality imported fittings, the K1-8 features dryseal pipe threads designed to minimize potential leak paths and provide sufficient clearance for tightening flare nuts. Each unit includes a dedicated fiber gasket to ensure a positive, leak-proof seal under pressure. Built to meet AHRI standards and SAE J513 specifications, this brass refrigerant adapter is fully compatible with copper, aluminum, and steel tubing, making it a versatile addition to any contractor?s service kit.

Key Benefits

• Precision Machined Brass: Constructed from 65/35 brass for maximum durability and reduced risk of stress cracking during high-torque applications.
• Leak-Proof Seal: Includes a high-quality replacement gasket to maintain vacuum integrity and prevent refrigerant loss during transfer.
• Broad Compatibility: Seamlessly adapts 1/2" NPS cylinder valves to 1/4" male flare, making it compatible with most standard refrigerant charging hoses.
• Field Reliability: Engineered with long dryseal threads that allow for easy assembly and "make and break" service without stripping.

Common Questions

Can I use this adapter for high-pressure refrigerants like R-410A?
Yes, the K1-8 is rated for high-pressure refrigeration service, though the fiber gasket should be inspected regularly for wear to ensure a secure seal.

Does this fit all refrigerant tanks?
This adapter is specifically designed for 1/2" NPS cylinder connections. Always verify your drum's valve size, as some larger or specialized tanks may require a 3/4" drum adapter instead.

Is a thread sealant required for installation?
While the K1-8 includes a gasket for the primary seal, using a compatible refrigerant thread sealant can provide an extra layer of protection against micro-leaks in high-vibration setups.
