247 fittings are made from 6061-T6 aluminium and CNC machined to ensure a precise, professional quality finish every time. Our 400 series push lock fittings are designed to use with our 400 series push lock hose which is E85 and methanol compatible. The Full flow one-piece design offer superior strength along with an uninterrupted flow. All our fittings undergo a forging process for added strength and durability then hand polished for that quality finish. 247 doesnt just sell hose and fittings, we know hose and fitting.
