Just want to make sure this fitting will work with my existing 3/8" compression setup. It's gotta be a tight seal, you know?

This Midland Industries fitting is designed to provide a reliable connection specifically for hydraulic applications. It's a 3/8" compression to 1/8" female connection.

got a 3/8 compression line and need to tie into a 1/8 female port. is that what this fitting is for?

Meant for joining a 3/8 compression connection to a 1/8 female connection, this Midland Industries S66-6-2 fitting is a simple way to bridge those two sizes in a hydraulic hookup.

Question by: Bonnie H on Jan 18, 2026, 5:39 PM

what exactly is the S66-6-2 fitting used for, and does it connect compression tubing to a female threaded port?

Answer by: Customer Support on Jan 20, 2026, 12:37 PM

That's exactly what it does. The S66-6-2 is a compression to female connector, meaning one end accepts a compression tube fitting and the other end connects to a female threaded port. The sizing is 3/8 inch on the compression side and 1/8 inch on the female connection side. It's a Midland Industries piece, so the build quality is solid for hydraulic line work where you need to transition between those two connection types.
