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 operational and burst pressure rating of the BRLK-18-14, 1/8 x 1/4 compression fitting, PCJOB02818, 1806, Zone L, Brass?

what grade of brass do you use to manufacture MTA3-1/4-1/4-BR Model
This question will require addition effort so please send your request to temp@omega.com for follow up.

Is the OmegaLok adapter Item# SSLK-14-14, 1/4" all the way through or is there a stop?
Thank you for your inquiry. This compression fitting is designed to accept a 1/4" diameter probe with no stop and opening is all the way through for probe insertion into a process.

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?
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.
Date published: 2022-09-20
What pressure will these compression fittings hold with a sheet type thermocouple
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 temp@omega.com to review but certainly a few hundred PSI can be expected.

Can this fitting be used to insert a 0.25 inch metal tube into a larger polycarbonate tube?
