Description: FLUKE-700-2013 ,STRAP, PRESSURE MODULE
Here is some information on adapters:
Notes: The module connection is 1/8 inch female NPT that is slightly modified to ensure full insertion of the adapters with o-rings (no thread tape required when using the supplied adapters). The 1/8 NPT male adapters are slightly under-sized to also ensure full insertion into the pressure module. If you are using one of our adapters with an o-ring seal, then you do not need sealing tape. If you use other 1/8-27 NPT threaded fittings (e.g Swagelok) then use sealing tape.
