Rated 5 out of 5 by from A+ Company and products This company has been very consistent with their customer service, availability, and pricing. I have never had an issue with them being late or having to move out parts I have asked for. This is a great company and I look forward to doing more business with them.

What is the thru hole diameter of the 1/8NPT to 6mm compression fitting? We are trying to use for a 5mm probe that has a 6mm collar for the fitting (need the 5mm diameter to go through the fitting). What is the rated pressure of the fitting?

Asked by: JE345
The SSLK-M60-18 has an opening to accept a 6mm diameter tube. Omega cannot make a recommendation for any other diameter and does not place a pressure rating either.

What pressure will these compression fittings hold with a sheet type thermocouple

Asked by: ThatGuy
Omega does not put a pressure rating on these fittings because there are many variables like tube wall thickness and temperature. You would need to send the exact part numbers to to review but certainly a few hundred PSI can be expected.
