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.

Fitting for Harsh Conditions
These fittings have stood up to some pretty harsh environment conditions and lasted well.

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?
No data available. It is dependent on the probe used in application.

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?
Thank you for your inquiry, Yes this fitting will except a 0.25 inch metal tube
