Navy DA solution

[Bryan]

I got a piece of neoprene cord stock from McMaster Carr that was rated at 50 durometer in hardness. I got it in 7mm diameter as opposed to the standard 1/4" or 1/2" pieces that I had been trying. Then I trimmed the length to so that it stuck up above the seat base about 1/32" like I remember the original did.
I have the IP set right around 95-100psi and everything seems to be cool. It breathes as well as the old guy should and has no leaks!!

Dan, your recommendation for 2 1/2 turns out on the adjustment screws on the horseshoe are right on the money!!! 2 turns and it's dang hard to breathe.....3 turns and it free flows.

Thanks to everyone for all their help!!

Cool! I'll print this and keep it for my records.

I went to www.mcmaster.com/ and saw:

"O-Ring Cord Stock" with english measure diameters. I didn't see 7 mm. Is this the same stuff? What exactly is it that I am looking for?

System of Measurement Inch
Material Neoprene
Durometer Shore A: 65-75
Operating Temperature Range -40° to +212°F

Maximum Continuous Length 100'
