This Jet Air is all rebuilt with new silicone diaphragm, yellow hoses, one way valves, black straight mouthpiece, and rubber duckbill.  This reg has been test dived in the pool and works great.  This single stage design by US Divers is the AK47 of regulators.  The hoses, mouthpiece and repro decal are all from VDH, so you know the quality is top notch.  Just look at the internals on this bad boy.
