JB NS4-14 7/8" SAE Flare Nut the T3-6C provides the mechanicalThe JB NS4 14 7 8" SAE Flare Nut is a heavy duty, short type forged flare nut engineered for high pressure refrigeration and ACR applications. Unlike standard cast fittings, this brass flare nut is manufactured from premium grade C360 and C370 brass (65% copper, 35% zinc) in the USA, providing superior tensile strength and eliminating the risk of stress cracks under extreme temperatures. Designed for a 7 8" SAE 45 degree flare connection, it ensures a
