The 20HB-20MP STRAIGHT is made from steel, offering good durability for outdoor use, but consider applying a protective coating if it'll be exposed to harsh weather regularly.

trying to swap out a fitting, is this one the straight steel barb to 1-1/4 male NPTF?
Answer by: Customer Support on Dec 1, 2025, 6:52 AM
For a straight barb-to-pipe-thread connection, this fitting matches a 1-1/4 inch tube OD hose barb on one end and a 1-1/4-11-1/2 Male NPTF thread on the other, built to the SAE J476 thread specification.
