Light weight aluminum adapters by Phenix Industries are designed for leak-proof sealing with any manufacturers hose ends.
excellent and saved the day.
While it doesnât state so, this is a 2-piece âswivelâ fitting so donât be surprised. Talking to manufacturer, the two-piece swivel fitting is required for aviation applications because the male side is allowed to swivel (or rotate) after locking into the male fitting you have inserted into female side. The female side then is allowed to turn around the male fitting you have inserted. If it wasnât two part swivel, the mating surfaces would score each other as you tightened down, increasing risk of leak. So two piece swivel, C431-4, is what you want for aviation.
Very nice item! Great quality and very use full in changing to a different size. I have used 4 on my build
Ordered 2 of these. Same part number on package but they were different parts. The shape of the fittings were different and one had an O-ring. They were functionally the same but obviously not...
This does not require an O-Ring. When you screw this together, it should be able to seal itself just fine.
Per the listed chart, that is correct. C431-4 has a -4 female, and -3 male thread.
