Brass Flare Short Nut
Brass Flare Short Nut
030-DFSN
Flare fittings in refrigeration, HVAC, gas, and fluid transfer systems are secured with the precision-engineered Brass Flare Short Nut. Its short length and compact form enable installation in confined areas while preserving sturdy and dependable flare connections.
Even in harsh industrial settings, the Brass Flare Short Nut offers exceptional mechanical strength, corrosion resistance, and a long service life because it is made from superior forged brass alloys like CW617N or C37700. A secure metal-to-metal seal that stops leaks and preserves system integrity is created by the precisely machined threads, which guarantee precise contact with flare fittings.
This small nut is frequently used in gas pipes, HVAC systems, refrigeration systems, and hydraulic equipment where compact fittings and reliable flare connections are needed.
