Midwest Fasteners Solid Brass Tube Insert Fitting

Midwest Fasteners Solid Brass Tube Insert Fitting

The Midwest Fasteners Solid Brass Tube Insert Fitting is a solid brass insert built to sit inside the bore of flexible or soft tubing, giving the tube wall rigid internal support so it does not collapse when a compression fitting clamps down from the outside. This insert fitting is available across a size range from .080 through .370, covering .080, .095, .163, .187, .250, and .370, so you can match the insert to your tubing's actual inside diameter rather than guessing at a one-size-fits-all part. Each insert is machined from solid brass for corrosion resistance and the durability to handle repeated assembly and disassembly on tubing lines, and every size in the range is sold as an individual insert fitting so you can stock exactly what a given job calls for.

Key Features

• Size Range: Insert sizes span .080, .095, .163, .187, .250, and .370 to match a wide range of tubing inside diameters.
• Material & Finish: Solid brass construction with a natural brass finish for corrosion resistance and long service life in tubing applications.
• Type: Insert fitting designed to sit inside the tube end, supporting the tube wall against compression-style connections.
• Form Factor: Compact insert profile that fits inside the tube bore rather than clamping around the outside, preserving tube roundness under clamping pressure.
• Individual Stocking: Sold as an individual insert fitting per size, so you can stock the exact size and quantity a job requires without committing to a larger pre-packed assortment.

Technical Specifications

• Refer to manufacturer documentation for complete technical specifications.

Typical Applications

• Reinforcing tube ends before installing compression fittings
• Maintenance and repair of tubing assemblies in plumbing and fluid-line work
• Fabrication projects requiring a stable, non-collapsing tube connection point
• Replacement of worn or damaged brass inserts on existing tubing runs across multiple tubing diameters

Why Midwest Fasteners?

Midwest Fasteners machines this brass insert fitting to consistent sizing across the full .080 to .370 range, so the part you order today matches the one you reorder later, regardless of which size your tubing requires. Solid brass construction helps the insert resist corrosion in tubing applications where metal-to-metal contact with surrounding fittings is constant. For maintenance techs and fabricators who need a dependable, correctly sized insert fitting on hand across a range of tubing diameters, this part is built to be a straightforward, repeatable stock item rather than a one-off substitute, and the same consistent brass quality carries across every size in the .080 to .370 range so a reorder always matches the original.
