Snap-On Counselor II MT3100 Gas Analyzer sample hose replacement

[lschwarcz]

Hi everyone,

The sample hose for my Snap-On MT3100 Counselor II 4-Gas Exhaust Analyzer appears to be deteriorating.



Of course, the OEM hose, part number, "MT310020" isn't available. The only marking on the hose is, "2000 LB WP"

Searching for this on Google shows it to be a high pressure hydraulic hose that sells for $3 and up per foot.

Does anyone know if that's the correct replacement hose for this? Is this really a high pressure situation?

As you can see from the above image, the hose is only secured to the end by being crimped to the fitting.

Any recommendations or suggestions for a replacement hose? I'm assuming that the length isn't critical and I can buy what ever length works for my shop.

Thanks in advance!
Larry.

EDITED: Oh, and some of the hoses I found mention being either conductive or non-conductive. Mine doesn't seem to be conductive using my ohm meter.

Kinda guessing that chemical resistance (Teflon/PTFE liner???) and/or high-temperature resistance are the only real "requirements" aside from being able to clamp/seal to the rest of the system.

The bigger question, is where are you finding replacement O2 sensors for that thing? I thought Snappy disowned equipment that old; and the sensors are a "consumable".

Thanks for the hose info!

As for the O2 sensors they're out there but not cheap. They seem to run about $80 - $100 USD. And, once the package is opened they last about 6 months regardless of how much you use it.

The good news is that since all I want out of this is to set my air/fuel ratio I don't need it! Thanks to engineer2 for letting me know about this!

If you need to find one you need to search for, "Class R22 Oxygen Sensor."
