Question by: Shane H on Nov 14, 2025, 5:00 PM
trying to hook up a 2.5 inch female NPT line to a 2.5 inch male NST fitting, is that what this adapter does?
Answer by: Customer Support on Nov 16, 2025, 12:49 PM
It bridges those two thread types in one piece, with a 2.5 inch FNPT connection on one side and a 2.5 inch MNST connection on the other.
Question by: Brent H on Jun 8, 2025, 10:46 AM
What kind of connection does this adapter have on each end, and is it all brass throughout?
Answer by: Customer Support on Jun 10, 2025, 6:01 AM
Both ends are brass, no mixed materials. One side is a 2.5 inch female NPT thread and the other is a 2.5 inch male straight thread. Dixon makes it as a full brass unit, so you're not dealing with any cast iron or aluminum in the body. Solid choice for jobs where corrosion is a concern.
Question by: Neal T on Dec 21, 2025, 2:44 PM
Will this adapter hold up if I'm using it for, like, hooking up a water pump?
Answer by: Customer Support on Dec 23, 2025, 6:44 AM
Constructed from durable brass, this Dixon adapter is suitable for industrial applications including water pumps.
