Boshart BH 125 No-Lead Brass Barb x MPT Adapter Fitting

The Boshart BH 125 No-Lead Brass Barb x MPT Adapter is a rough-in fitting built for plumbers and contractors who need a reliable transition between hose or tubing and male iron pipe thread (MPT) connections. Machined from No-Lead brass, this hose barb adapter is suitable for use with various hose and tubing applications found in residential and light commercial plumbing systems. This adapter is offered across a full size range from 1/4" through 1" (available in 1/4", 3/8", 1/2", 5/8", 3/4", and 1"), so crews can standardize on one fitting design for multiple line sizes. The barbed end accepts push-on hose or tubing while the MPT end threads directly into a female pipe fitting, giving installers a fast, dependable way to convert between pipe and flexible line without soldering or additional couplings. Boshart supplies this adapter in bulk packaging of 25 pieces per case, making it a practical stock item for plumbing wholesalers, service trucks, and new-construction crews who go through fittings in volume.

Boshart BH-125-0404NL – Frequently Asked Questions

1) On the Boshart BH 125 barb x MPT adapter, is the size the hose barb size or the pipe thread size?
Both ends match on most of the range. The BH 125 is a barb by male pipe thread adapter, and the part numbers pair the two ends: 1/4 inch barb to 1/4 inch MPT (BH-125-0404NL), 3/8 to 3/8 (BH-125-0606NL), 1/2 to 1/2 (BH-125-0808NL), 3/4 to 3/4 (BH-125-1212NL) and 1 inch to 1 inch (BH-125-1616NL). The exception is the 5/8 inch, BH-125-1008NL, which pairs a 5/8 inch barb with a 1/2 inch MPT. If you are running 5/8 hose into a 1/2 inch female fitting, that is the one you want.
2) Can I use a Boshart BH 125 brass barb adapter on potable drinking water lines?
The BH 125 is machined from No-Lead brass, which is the material plumbers specify for potable water supply work, and Boshart lists it for residential and light commercial water supply rough-in. Note it does carry a Prop 65 lead warning, which is standard labeling on brass fittings sold into California.
3) Do I need a clamp with a barbed brass hose adapter, or does the barb hold on its own?
Plan on a clamp. The barb end is a push-on connection and Boshart specifies it be secured with a clamp; the barb resists pull-out but the clamp is what makes the joint hold pressure. Clamps are not included, so order stainless or pinch clamps sized to your hose OD along with the fittings.
4) Should I use a barb x MPT adapter or a compression or soldered fitting for a hose-to-pipe transition?
A barb x MPT adapter like the BH 125 is the choice when one side of the joint is flexible hose or tubing. It converts that flexible line straight into a female threaded fitting, valve or manifold with no soldering and no solvent welding, so it works on a live service call and on plastic tubing that cannot be soldered. If both sides of the joint are rigid copper or rigid pipe, a barb is the wrong part and you want a soldered, press or threaded adapter instead.
5) Will a barb x MPT adapter thread into a female NPT valve or manifold port?
Yes. The threaded end of the BH 125 is male pipe thread, so it goes into any standard female-threaded fitting, valve or manifold of the matching size. Use thread sealant or PTFE tape on the taper thread; the barb end is not threaded and takes hose or tubing instead.
6) How is the Boshart BH 125 adapter packaged, and can I buy just one?
It comes in bulk cases of 25 pieces per size. That is set up for supply houses, service trucks and new-construction crews going through fittings in volume rather than a one-off repair.
7) What sizes does the Boshart BH 125 brass barb adapter come in?
Six sizes, covering 1/4, 3/8, 1/2, 5/8, 3/4 and 1 inch. That spans the common appliance and fixture supply tubing sizes up through 1 inch hose, so a crew can standardize on the one fitting design across all the line sizes on a rough-in.
8) Where is the Boshart BH 125 adapter made?
The BH 125 No-Lead brass barb adapter is manufactured in China for Boshart Industries. Worth knowing if you are bidding a job with domestic-sourcing requirements.
