Inch Cascade Brass Tubes with Threads on Both Ends

These inch cascade brass tubes are used inside injection mold cooling circuits where engineers implement cascade flow plumbing with nipple-type cascades. Instead of a single distribution loop, the tube sections help step the coolant through multiple mold zones while maintaining a compact internal layout.

• Automotive component molds: For long, thin-cavity blocks and runner-adjacent cooling, the tube’s threads on both ends support straightforward in-line connections between cascade nipples and tubing runs.
• Industrial housing molds: When multiple cooling “stations” are required across a part footprint, the available tube O.D. and I.D. sizes help match the desired flow path and spacing between cooling features.
• General mold interior cooling retrofit: The inch-threaded interfaces improve compatibility with existing cascade plumbing components, reducing rework during maintenance or upgrades.

Solid brass construction is well-suited for these applications due to its practical corrosion resistance in typical cooling-water environments and its reliable threaded connection behavior for repeatable assembly.

The product uses solid brass for the tube body, selected for its balance of machinability, dimensional stability, and corrosion resistance in cooling-plumbing systems. Brass typically offers good resistance to common corrosion mechanisms encountered in aqueous cooling lines, supporting long-term operation of internal mold channels.

Because no heat-treatment or hardness specification is provided for this brass variant, it should be treated as a non-hardened tubing material where wear performance is driven more by flow cleanliness and corrosion control than by tool-steel-style hardness targets.

• Wear vs. toughness trade-off: Brass generally provides stable strength without the high hardness/wear profile of hardened tool steels; therefore, it is best for plumbing connections rather than abrasive wear surfaces.
• Manufacturing process: Expect conventional tube fabrication (drawing/extrusion) followed by thread cutting at both ends to achieve the stated thread sizes.

To select the correct cascade tube, match both the outer geometry and the thread interface to the rest of your nipple-type cascade plumbing. Start with the required tube O.D.: available options are 0.125 in, 0.187 in, 0.250 in, and 0.312 in.

• Match thread size: Choose the tube thread size that fits your cascade nipples and fittings: #5-44, #10-32, 1/4”-28, or 5/16”-24.
• Check flow clearance: Verify the tube I.D. against your flow-path intent: 0.061 in, 0.123 in, 0.170 in, or 0.210 in. Using an I.D. that is too small can restrict coolant flow in the cascade stage.
• Fit and tolerance: Because threaded joints rely on standard thread profiles, proper compatibility is primarily ensured by selecting the correct thread size. For assembly, allow for normal thread fit clearances and avoid forcing mis-matched O.D./thread combinations into restricted mold interiors.

Dimensions are configured by the specific size variant (O.D., I.D., and thread size are not independent—select the combination that matches your cavity/core routing and the cascade nipples used).
