inflator hose

My husband and I just received our new BCDs. My Zeagle comes with a 250psi hose (separate packaging, no brand) and his ScubaPro comes with a 420psi hose already attached to the BCD (no integrated Air2). What’s the difference and should I or he switch to a higher/lower PSI hose? Thanks!

I noticed one of my wings (XDEEP Hydros 40) came with a really nice and flexible rubber LP inflator hose. I have a bunch of other spare rubber hoses and they all seem significantly stiffer compared to that one. So I was just curious if there was somewhere I could buy these nicer flexible hoses?

Attention gearheads! Thanks for those of you who have helped me thus far. I recently purchased a new QD adapter and LP hose for my old Oceanic Islander BC with integrated 2nd stage on the inflator hose. DGX has two different adapter fittings options, and I got the Aqualung option as it was...

good afternoon! I’m putting together some older (shop tested) gear and have run into an unexpected problem with compatibility. Aqualung Conshelf XIV QD inflator hose doesn’t fit the port on my Oceanic Islander bcd... why???? Should a get a new hose or a new and adapter? THANK YOU ALL

Suggestions on where I can locate this replacement part are most welcomed!
