FAQ
What hose fits the 5/8 in. barb?
Push-on hose with a 5/8 in. ID rated for your media and pressure.
Why is the barb larger than the thread?
It steps a high-flow 5/8 in. hose down to a 3/8 in. NPT port, common on equipment with mismatched sizes.
Do I need a clamp?
The push-on barb grips at low pressure; add a clamp at higher pressure given the larger hose.
What thread is the male end?
3/8-18 male NPT (tapered). Use thread sealant.
