Boshart No-Lead Push-Fit x MPT Brass Adapter
The Boshart BPF-MA is a no-lead brass push-fit x male pipe thread (MPT) adapter built for potable water and hydronic heating rough-in work, including new residential and commercial construction. This family is available across a range of sizes — 3/8", 1/2", 3/4", and 1" — to match the copper, CPVC, and PEX tubing outer diameters commonly used in rough-in plumbing. Every size is approved for use underground and behind walls, with or without access panels, and is well suited for wet, hazardous, or dry repair work on existing plumbing where draining the system for soldering is difficult. The push-fit connection accepts copper, CPVC, and PEX tubing in any combination, making it a fast, tool-free way to transition rough-in tubing to male threaded connections at valves, fixtures, or appliances.

Boshart BPF-MA03NL – Frequently Asked Questions
1) Can the Boshart BPF-MA push-fit adapter connect copper, CPVC and PEX, or do I need a different fitting for each material?
One fitting covers all three. The push-fit end of the Boshart BPF-MA accepts copper, CPVC and PEX tubing in any combination, so you stock one size instead of three material-specific adapters. The other end is male pipe thread for connecting to threaded valves, fixtures or appliance stops. No solder, flux, glue, clamps or unions needed.
2) Can a push-fit adapter be installed behind a wall or buried underground without an access panel?
Yes. Every size of the Boshart BPF-MA is approved for use underground and behind walls, with or without access panels. That is the main practical difference from push-fit fittings restricted to accessible locations, and it is what lets you use it on a concealed branch instead of opening the wall for a sweat joint.
3) Can I make a repair with this fitting on a line I cannot fully drain?
That is one of the situations it is built for. Because there is no soldering involved, the Boshart push-fit x MPT adapter works for wet, hazardous or dry repair work on existing plumbing where draining the system for a torch joint is difficult or unsafe. Useful on occupied buildings where you cannot shut down a riser long enough to dry it out.
4) What sizes does the Boshart push-fit x MPT brass adapter come in?
Four sizes: 3/8 inch (BPF-MA03NL), 1/2 inch (BPF-MA05NL), 3/4 inch (BPF-MA07NL) and 1 inch (BPF-MA10NL). The size matches the outside diameter of the copper, CPVC or PEX tubing going into the push-fit end. Most residential rough-in branch work lands on 1/2 and 3/4; 3/8 is typical for fixture supply runs.
5) Is the Boshart BPF-MA adapter safe for potable water lines?
It is a no-lead brass body made for potable water, and it is also used on hydronic heating connections. Note that the product does carry a Prop 65 lead warning, which is standard for brass plumbing components sold into California.
6) What is the difference between a push-fit x MPT adapter and a push-fit coupling or FPT adapter?
The MPT version puts male pipe threads on the outlet, so it threads directly into a female port on a valve, fixture stop, water heater nipple or appliance connection. A coupling joins two lengths of tubing instead, and a female-thread adapter is what you want if the mating part is a male nipple. Choose the Boshart BPF-MA when your tubing has to terminate at a female threaded port.
7) Do I need a special tool or crimp ring to install the Boshart push-fit adapter?
No. The push-fit end seals when you push the tubing in, so there is no crimp ring, clamp, union, flux, solder or glue involved. Standard practice with any push-fit connection still applies: cut the tube square, deburr it, and insert to full depth. For PEX, follow the manufacturer's guidance on stiffener use for the tubing you are running.
8) Can the fitting be turned after the tubing is pushed in, or is the thread position fixed?
It rotates after assembly. You can spin the Boshart BPF-MA to line up the male thread with a valve or appliance connection once the tubing is seated, which matters in a stud bay or tight mechanical closet where you cannot get a wrench on it or reposition the pipe.
9) Where is the Boshart BPF-MA adapter made?
China. The body is no-lead brass and the line is sold under Boshart's BPF-MA series designation, with part numbers running BPF-MA03NL through BPF-MA10NL.
