I am inquiring about what is the insertion depth required for tubing for the straight and 90 degree 7/8 fittings. It is not listed on any documents with the fittings or online.

If you can get back to us via email with the exact part numbers you are inquiring about I can get with the warehouse and send over a list with these specifications 😊 Kind Regards, Customer Support ✨ Supplying Demand
