Ace-Thred Coupling, Reducing, Nylon or PTFE, Ace Glass Incorporated
Fittings and Connectors
Reducing Ace-Thred coupling that can be used to couple threading columns together, or to end fittings with single o-ring seal for leak-tight engagement

This coupling has "front seals," which means that the o-ring on the Ace-Thred connections is located at the BOTTOM of the threads rather than at the top. This provides a better, more consistent seal. This is critical for pressure applications, and it also prevents viscous materials from migrating up into the threads.

Can also be used for coupling manifolds. One end is threaded for the next smallest diameter. Ace-Thred size listed refers to inside diameter of threads and corresponds to the column diameter.

Ordering information: Supplied with two FETFE o-rings. FETFE is an Ace Glass exclusive compound, a fluoroelastomer with TFE additives. It has good compression set along with excellent temperature and chemical compatibility. FETFE is a USP Class VI material.
