Hex Key Cascade Assemblies (Inch)

These hex-key cascade assemblies are used inside injection molds to create compact, minimum-clearance cooling or tempering circuits where straight-line plumbing would not fit. The hex-key connection style supports fast installation and service in restricted mold cavities, helping maintain consistent water routing without disassembling large mold sections.

• Automotive and appliance housings: Ideal for tooling that uses dense cooling layouts around thick-to-thin transitions, where multiple junctions must be reached with a standard hex key while preserving clearance for inserts and ejector components.
• Medical device housings: Suitable for stable coolant flow paths requiring cleanable, corrosion-resistant plumbing components to support repeatable thermal performance over production runs.
• Electronics enclosures: Works well when cascade-style flow routing is required near the parting line or within narrow mold windows, enabling efficient thermal control with minimal interior packaging.

The stainless steel tube and nipple included with this variant help ensure efficient connection and stable fluid routing in tight-space layouts.

This assembly is built around stainless steel for the high-flow tube and the 2" stainless steel pipe nipple, supporting corrosion resistance in typical mold water/tempering service. A 12" stainless steel tube provides stable flow geometry, which helps reduce variability in cooling performance at junctions.

• Wear/impact behavior: Stainless steel offers strong resistance to corrosion and moderate surface durability for plumbing components exposed to repeated flow cycling.
• Toughness vs. hardness: For fluid-connector parts, corrosion resistance and dimensional stability are prioritized over extreme surface hardness; the assembly is not specified as a quenched-and-tempered hardened steel tooling part in the provided data.

Because no specific steel grade, heat-treatment state, or hardness (HRC) values are listed, hardness and HRC trade-offs cannot be confirmed from the available specifications. If you require a defined grade for validation (e.g., 304/316), share your target media and operating temperature and we can help align material selection.

Use the provided dimensional elements to match the cascade connection to your mold’s cooling circuit layout. This variant includes a 12" stainless steel tube and a 2" stainless steel pipe nipple, which should be checked against the available straight run length and the connection space at the junction location.

• Tube length fit: Confirm the 12" tube can be routed without interference to inserts, vents, lifters, or ejector hardware while maintaining minimum-clearance access for installation/removal.
• Nipple connection space: Verify the 2" nipple installation envelope aligns with your manifold/port geometry and that sufficient reach exists for sealing and wrench/hex-key engagement.
• Hex-key accessibility: Ensure the cascade area provides clearance for the standard hex-key drive so the assembly can be serviced after wear or contamination events.

No tolerance values or metric/inch thread or sealing specifications are included in the provided data. For correct fit, dimension your manifold interfaces to the assembly’s connection points and allow for practical installation clearances and gasket/connector compression as used in your shop standard.
