Switching out inflators on BCD

[AlanJoz]

I have a scubabro knighthawk and would prefer to have an inflator like the one I posted below. Is this possible to do and would it cause an issues?

It should just be a couple cable-ties. If your Knighthawk has a pull-down left shoulder dump, there will be a cable inside the corrugated hose that you also connect to a pin on the new inflator - centered in the opening - you can see the metal pin here:.

What diversteve said.
But why exactly? The stock inflator is a better unit. The posted one is pretty old fashioned.

Doesn't necessarily have to be that one. I'm just looking for an inflator where the inflate button is on the top where you can hold it up and know your thumb is on the inflate button vs having both buttons side by side. Which inflator button would you recommend?

45-degree Oral Power Inflator

When you change the zip tie, make it as tight as you can by hand. Then use a pair of needlenose pliers and twist it for another 1-2 clicks.

45-degree Oral Power Inflator

The one I use. Cheap enough to be disposable. Cheap tools and parts available to rebuild if so inclined.

Thanks for the help guys. I really appreciate it. I like the 45-degree one posted above.

cheap enough to keep a spare in the save a dive kit! personally swapped out AIR2s on two *hawk BCDs and replaced em with DGX PIs when we swapped over to necklaced secondaries.

snip the zip tie, wiggle out the old inflator, remove the pin retaining the jet dump wire, attach jet dump wire to new inflator, insert the assembly back into hose (a tiny dab of liquid soap makes this a lot easier on the SP corrugated hoses), and attach new zip ties.

while you've got everything apart, might want to consider swapping out zip ties for clamps: Clamp, Corrugated Hose, each (two required)

Sweet! Done. Order is in. Thanks for the help guys.

Those clamps are to wide for my knighthawk hose. Inflators looks good though!
