Boshart BC-66-0608NL No-Lead Brass 3/8" CP x 1/2" FPT Compression Adapter

The Boshart BC-66-0608NL is a no-lead brass compression adapter sized 3/8" CP (compression) x 1/2" FPT, built for low to medium pressure rough-in applications. This fitting transitions compression tubing to female pipe thread and is suitable for use with copper, brass, aluminum, plastic, CPVC and PEX tubing carrying gasoline, grease, oil, water, vacuum and air lines. As a no-lead brass fitting, it is intended for plumber and contractor rough-in work where a reliable compression-to-threaded transition is needed behind the wall or under the floor.

Key Features

  • Trade Size: 3/8" CP (compression) x 1/2" FPT for connecting compression tubing to female-threaded pipe or fixture stops.
  • Durable Construction: Solid brass body resists corrosion and holds up to repeated compression tightening in rough-in installations.
  • No-Lead Alloy: Manufactured from no-lead brass, matching the fitting for potable-water-adjacent installations where a no-lead alloy is required.
  • Compression Connection: Compression-style connection on the 3/8" CP end provides a mechanical, solder-free joint on tubing.
  • Female Pipe Thread Outlet: 1/2" FPT outlet threads directly onto standard male iron pipe thread (MIP) fittings, valves, or stops.
  • Broad Tubing Compatibility: Works with copper, brass, aluminum, plastic, CPVC and PEX tubing for versatile rough-in use.
  • Vibration Resistance Tip: In applications where vibration is present, use of a long nut is recommended for extra holding resistance.

Boshart BC-66-0608NL – Frequently Asked Questions

1) What size connections does the Boshart BC-66-0608NL compression adapter have?
It's a 3/8 inch compression (CP) inlet to a 1/2 inch female pipe thread (FPT) outlet. The compression end takes 3/8 inch OD tubing with a nut and sleeve; the 1/2 inch FPT end threads onto standard 1/2 inch male iron pipe thread on a valve, stop, or nipple. So it both transitions size and changes joint type in one fitting.
2) Can I use this brass compression adapter on PEX or CPVC, or is it copper only?
Not copper only. The BC-66-0608NL is rated for copper, brass, aluminum, plastic, CPVC and PEX tubing, so long as the tube is 3/8 inch OD to match the compression end. With PEX you still want a stiffener insert in the tube so the ferrule has something to compress against.
3) Is the Boshart BC-66-0608NL adapter lead free for potable water?
The body is no-lead brass, which is the alloy specified for potable water service lines. That's what lets it sit in a domestic water rough-in rather than being limited to non-potable duty.
4) Is this the right fitting to connect a supply tube to a 1/2 inch angle stop?
It works the other direction from what most people expect. The 1/2 inch FPT outlet screws onto a male threaded nipple or valve, and the 3/8 inch compression side accepts the tubing. If your stop already has a male 1/2 inch IP thread and you're running 3/8 inch tube off it, this adapter is the transition. If your stop instead has a female inlet, you need a male-threaded adapter, not this one.
5) Will a compression adapter hold on a line that vibrates, like a pump or appliance connection?
Boshart's own guidance on this adapter is to use a long nut where vibration is present, for extra holding resistance on the tube. A standard short compression nut grips less tube length and can work loose under sustained vibration. On a pump discharge or anywhere with pulsation, spec the long nut.
6) What pressure service is this compression adapter intended for?
Low to medium pressure rough-in work. It's a mechanical compression joint, not a brazed or threaded high-pressure connection, and Boshart lists it for water, air, vacuum, gasoline, grease and oil lines in that pressure band.
7) Do I need to solder or use a torch to install this fitting?
No. The 3/8 inch end is a compression connection, a solder free mechanical joint made by tightening the nut over a ferrule. That makes it usable in finished or confined spaces where an open flame isn't allowed, and it can be broken down and remade if the fixture changes.
8) How is the Boshart BC-66-0608NL packaged for a supply house or job cart?
It ships 25 pieces to a pack, which suits a service van or a shop bin rather than one-off replacement. Manufacturer part number is BC-66-0608NL, and the country of origin is China.
