Zoro Select 7808 Adapter Purpose

The Zoro Select 7808 is a stainless steel straight adapter designed to connect a 3/8 inch NPT female thread to a 1/4 inch NPT female thread. It suits industrial plumbing systems requiring a durable, high-pressure transition between different pipe sizes.

Verify Threads and Pressure Rating

Confirm that both ports in your existing system use NPT threads with 18 threads per inch to match the adapter ends. Ensure the system operating pressure does not exceed 900 psi, which is the maximum rating for this Schedule 160 component.

Fits Schedule 160 Stainless Piping

The 304 stainless steel construction resists corrosion in harsh fluid environments and matches Schedule 160 pipe wall thickness. It joins two female-threaded components directly, eliminating the need for a separate coupling or bushing in the line.

Questions about this item

What comes with the 7808 adapter and do I need to buy thread sealant separately?

The box contains the stainless steel straight adapter only; pipe thread sealant or tape must be purchased separately.

How do I choose between the 3/8 NPT and 1/4 NPT ends on this Schedule 160 fitting?

Both ends are present on the same adapter — the 3/8 inch female thread connects to the larger pipe and the 1/4 inch female thread connects to the smaller pipe.

What does the 900 psi rating mean when the adapter is installed in a 304 stainless system?

It indicates the maximum operating pressure the Schedule 160 fitting can safely handle when properly assembled with compatible 304 stainless components.
