Boshart BC 61 Brass Compression Fitting Nut, Multi-Size

The Boshart BC 61 Brass Compression Nut is a rough-in plumbing component designed for use with compression fittings on low to medium pressure lines. Machined from brass, this compression nut is available in 1/4" and 3/8" sizes and is suitable for gasoline, grease, oil, water, vacuum, and air line applications. It mates with copper, brass, aluminum, plastic, CPVC, and PEX tubing, making it a versatile part for plumbers and contractors who need to complete compression joints in a variety of tubing materials. Sold in cartons of 25 for professional plumbers and contractors stocking rough-in fitting components, the BC 61 nut is a standard behind-the-wall part used throughout residential and commercial jobs to finish compression connections quickly and reliably.

Key Features

  • Size Range: Available in 1/4" and 3/8" sizes to match common compression fitting applications.
  • Durable Construction: Brass body resists corrosion and holds up under repeated tightening cycles on compression joints.
  • Compression Fit: Designed to complete a compression connection, drawing the ferrule down onto the tubing to seal the joint without soldering or solvent welding.
  • Broad Tubing Compatibility: Works with copper, brass, aluminum, plastic, CPVC, and PEX tubing, giving plumbers a single compression nut style for multiple tubing materials on a job.
  • Multi-Media Service: Suitable for low to medium pressure applications carrying gasoline, grease, oil, water, vacuum, and air lines.
  • Vibration Resistance Note: In applications where vibration is present, using a long nut in place of this style is recommended for extra holding resistance.
  • Bulk Packaging: Packaged 25 pieces per unit, making it practical for plumbing supply houses and contractors to stock for repeat use across multiple compression joints.

Boshart BC-61-04 – Frequently Asked Questions

1) What sizes does the Boshart BC 61 brass compression nut come in?
Two sizes: 1/4 inch and 3/8 inch. The 1/4 inch is MPN BC-61-04 and the 3/8 inch is BC-61-06. Size refers to the tubing OD the compression joint is being made on, so match the nut to the tube, not to the pipe thread behind it.
2) Will a Boshart BC 61 compression nut work on PEX or CPVC tubing, or is it copper only?
It mates with copper, brass, aluminum, plastic, CPVC and PEX tubing. That is why a lot of contractors keep one nut style on the truck instead of sorting by tube material. Note the nut only draws the ferrule down; on soft plastic tube you still need the correct insert/stiffener for that tubing system.
3) Does the BC 61 nut include a ferrule or sleeve?
No. The BC 61 is the nut alone, a brass compression nut sold as a rough-in component. The ferrule (compression ring) and the fitting body are separate items, so order those alongside it if you are building a joint from scratch rather than replacing a stripped or lost nut.
4) Is a short compression nut okay on a line that vibrates, like near a pump or compressor?
Where vibration is present, a long nut is recommended in place of this style for extra holding resistance on the tube. The BC 61 is the standard short pattern, fine for static rough-in runs behind the wall, but on a pump discharge, compressor line, or anywhere the tube is being worked back and forth, step up to the long-nut version.
5) Can I use this compression nut on a gas or oil line, or is it water only?
Service media listed for the BC 61 covers gasoline, grease, oil, water, vacuum and air lines, at low to medium pressure. It is not a high pressure part, and local code governs what is acceptable on fuel gas piping in your jurisdiction.
6) How is the Boshart BC 61 packaged, and can I buy just one?
It ships 25 pieces per carton. That suits a supply house or a contractor stocking rough-in components for repeat compression joints rather than a one-off repair.
7) Does the BC 61 brass compression nut carry a Prop 65 warning?
Yes, a California Prop 65 warning for lead applies. That matters if you are specifying for potable water in a jurisdiction with lead-content restrictions, or if you need to pass the warning through on documentation to an institutional or government customer.
8) Can I make a compression joint with this instead of soldering?
That is the point of it. The nut draws the ferrule down onto the tube to seal the joint mechanically, with no torch and no solvent weld. Useful on renovation work where you cannot get an open flame near finished surfaces, and on tubing like CPVC or PEX where soldering is not an option at all.
9) What is the BC 61 compression nut made of and how big is it?
Machined brass, 0.450 inches in height, and 0.020 pounds each. Brass holds up to repeated tightening cycles and resists corrosion, which is the reason it is used behind the wall where the joint will not be revisited.
