Frequently Asked Questions
The swivel connection prevents hose twisting, simplifies installation in tight spaces, and reduces strain on both hoses and pump ports.
Yes, the Graco 126432 is designed for high-pressure industrial fluid systems and meets OEM specifications for strength and reliability.
No. JIC connections seal on the 37° flare and do not require thread sealant. Only the NPT side should use sealant or PTFE tape.
Check your pump or equipment manual for connection sizes. If it specifies 9/16-18 JIC and 1/2" NPT, this fitting is a direct match.
