Replacement Heads for High-Flow Stainless Tubes - Inch

These replacement heads are used inside injection mold thermal-management systems that rely on cascade cooling, where fluid is distributed through a chain of cooling passages to maintain uniform mold temperature.

• High-flow stainless tube cascade sections: Install the head at the tube interface to restore flow stability after wear. The solid brass body supports consistent sealing and helps maintain the intended cascade performance.
• Product-heavy automotive and appliance molds: In applications that demand higher heat-removal capacity, matching the head to the existing high-flow stainless tube threads is used to regain higher throughput performance.
• Industrial heat-control housings and manifold upgrades: When upgrading or repairing cooling plumbing, the included brass pipe plug helps complete the head-to-tube connection for reliable operation.

Because this variant is made from solid brass and is supplied with a brass pipe plug, it is particularly suited for re-establishing a tight, stable connection in high-flow cascade layouts using inch-size tube hardware.

This replacement head is manufactured from solid brass, selected for dimensional stability at typical mold-cooling conditions and for its corrosion resistance in many water/glycol service environments.

• Machining process: Brass heads and the integrated installation features are typically turned and threaded to the required inch tube thread sizes, with a sealing interface prepared to mate with the cooling line.
• Heat treatment: Brass components are generally supplied in a machined (non–quenched and tempered) condition rather than hardened steel heat treatment, focusing on form/fit and seal performance.
• Performance trade-offs: Brass provides good sealing reliability and ease of fabrication, but it is not intended to replace hardened tool steels where extreme wear/impact would dominate.

Where higher abrasion resistance is required, stainless tube or hardened steel components may be used in the flow path; however, this brass head variant targets dependable interface sealing and cascade flow continuity.

Select the correct replacement head by matching both the pipe tap size (NPT) and the tube thread size used on the high-flow stainless tube assembly.

• Pipe Tap Size (NPT): Choose 1/8" or 1/4" to match the tapped connection in the mold’s cooling manifold or cascade segment.
• Tube Thread Size (in): Select from 1/4"-28, 5/16"-24, or 3/8"-24 based on the existing stainless tube thread specification.

To ensure proper fit, confirm thread type (NPT vs. tube thread) at the installation interface before ordering. If your system uses the specified tube threads, this head is designed to complete the connection with the included brass pipe plug, helping maintain the intended high-flow cascade throughput.

Tolerances are governed by the mating thread standards of the existing cooling hardware; aim for full thread engagement without cross-threading to preserve sealing integrity.
