Adapter Purpose

The Banjo HB038 connects a 3/8 inch hose barb to a 3/8 inch male NPT thread. It provides a straight, rigid joint for fluid transfer in plumbing and automotive systems. The fitting is moulded from black polypropylene for chemical resistance.

Suitable Installations

This suits installers joining flexible hose to a threaded port on pumps, tanks or valves. It is not for buyers who need a swivel or elbow orientation. It is not for buyers who require a vacuum-rated connection. It is not for buyers who need a different barb or thread diameter.

Critical Specification

The operating temperature range runs from -20 to 150 degrees Fahrenheit. This single limit decides whether the adapter survives the intended service. Exceeding it risks material failure and leaks.

Questions about this item

Does the Banjo HB038 adapter come with hose clamps or do I need to buy them separately?

The adapter is supplied as a single polypropylene fitting with a 3/8" barb and 3/8" male NPT thread; hose clamps are not included and must be purchased separately.

Should I choose this 3/8" barb version or look for a different size for my hose?

Select the HB038 when your hose has a 3/8" inside diameter; the barb and NPT thread are both sized for 3/8" connections.

What does the 150 degree F temperature rating mean for daily use?

The polypropylene body is rated for continuous service from -20 to 150 degrees F, so it handles hot water lines and seasonal cold without cracking.
