Boshart BC No-Lead Brass Compression Union Fitting

The Boshart BC is a no-lead brass compression union built for rough-in plumbers who need a reliable mechanical joint on low to medium pressure lines. This compression fitting is designed for use with copper, brass, aluminum, plastic, CPVC, and PEX tubing, making it a versatile connector for gasoline, grease, oil, water, vacuum, and air line applications behind the wall or under the floor. The BC union is available across a range of sizes from 1/4" up to 5/8" x 3/8", including 1/2 x 3/8", 1/4", 3/8", 3/8 x 1/4", 5/8 x 3/8", and 5/8" configurations, so plumbers can match the fitting to the tubing size on hand without switching connection systems. Constructed from no-lead brass, the union delivers a corrosion-resistant, code-aware connection point for tubing runs where a serviceable, non-permanent joint is preferred over a soldered or solvent-welded connection.

Key Features

  • Size Range: Offered from 1/4" through 5/8" x 3/8", covering straight and reducing size combinations for common tubing transitions.
  • Durable Construction: No-lead brass body resists corrosion and is suitable for the tubing materials it is rated to join.
  • Compression Connection: Mechanical compression joint allows quick installation and future disassembly without soldering or solvent welding.
  • Broad Tubing Compatibility: Compatible with copper, brass, aluminum, plastic, CPVC, and PEX tubing for flexible rough-in use.
  • Multi-Media Rated: Suitable for gasoline, grease, oil, water, vacuum, and air line applications at low to medium pressure.
  • Vibration Resistance Tip: Use of a long nut is recommended in installations subject to vibration for added holding resistance.
  • No-Lead Compliance: Manufactured to a no-lead brass specification for applicable potable-adjacent rough-in use.

Boshart BC-62-04NL – Frequently Asked Questions

1) What tubing can a Boshart BC compression union be used on?
The Boshart BC no-lead brass compression union joins copper, brass, aluminum, plastic, CPVC, and PEX tubing. Because it is a mechanical compression joint rather than a soldered or solvent-welded one, you can use the same connection system across mixed tubing on one job and take the joint apart later for service.
2) Does Boshart make a compression union that steps down from 1/2 inch to 3/8 inch tubing?
Yes. Three reducing unions are made: 3/8 x 1/4 inch (BC-62R-0604NL), 1/2 x 3/8 inch (BC-62R-0806NL), and 5/8 x 3/8 inch (BC-62R-1006NL). Straight sizes are 1/4 inch, 3/8 inch and 5/8 inch. So a 1/2 to 3/8 transition is a single reducing union, no adapter stack needed.
3) Can I use a compression union instead of soldering a copper line behind a wall?
That is what the BC union is for. It makes a mechanical joint on low to medium pressure lines, so no torch and no solvent cement, and it comes apart again if the run has to be serviced. Rough-in water supply, vacuum and compressed air, and fuel, grease or oil lines are all within its stated use. On permanent, fully concealed high-pressure work most plumbers still prefer a soldered or brazed joint, and local code may dictate whether a concealed compression joint is acceptable.
4) Will a Boshart BC compression union hold up on a line that vibrates?
Boshart recommends using a long nut where the installation is subject to vibration, which adds holding resistance on the tubing. That applies to things like compressed air drops and pump or equipment connections. A standard nut is fine on static supply runs.
5) What is the part number for the 5/8 inch Boshart brass compression union?
The straight 5/8 inch union is BC-62-10NL. The other straight sizes are BC-62-04NL for 1/4 inch and BC-62-06NL for 3/8 inch. Reducing versions use the BC-62R prefix, so a 5/8 x 3/8 is BC-62R-1006NL.
6) Can this compression union be used on a gas or fuel line?
Gasoline, grease and oil lines are among the stated applications for the BC no-lead brass compression union, along with water, vacuum and air, at low to medium pressure. It is not represented for natural gas or LP gas service, and fuel gas piping is governed by local code and requires fittings listed for that use.
7) How many Boshart BC compression unions come in a case?
Packaging is 25 each per case, which is how supply houses and service trucks tend to stock a common compression union. Size is chosen per variant, so a case is one size, not an assortment.
8) Where is the Boshart BC compression union made?
Country of origin is China. Buyers on government or institutional jobs with domestic-sourcing requirements should factor that in before specifying it.
