JWPH Cooling Circuit Plugs (150°C Heat Resistance)
JWPH Cooling Circuit Plugs (150°C Heat Resistance) are heat-tolerant sealing plugs designed to help maintain stable cooling circuit performance in high-temperature production environments. Compared to conventional plugs, they support continued use up to 150°C for dependable shutoff.
- JWPH sealing plug form for secure cooling circuit closure
- Upgraded heat resistance enables operation up to 150°C
- Fits multiple outer diameters (choose during ordering) for compatibility
- Used in mold cooling and industrial fluid cooling circuit assemblies

Product Guide
Application Scenarios+
JWPH cooling circuit plugs are used in injection mold interior cooling assemblies where fluid lines must be reliably sealed during molding cycles and maintenance. They are typically installed to close unused ports, cap drilled cooling channels, or isolate segments of a cooling circuit in mold-heating-cooling configurations.
In high-temperature automotive connector molds, stable sealing helps prevent coolant leakage that can upset thermal balance and affect cycle time. The plug’s 150°C heat resistance supports continued shutoff performance in production conditions where surrounding tooling temperature rises.
They are also applied in industrial hydraulic or coolant manifold circuits that feed mold cavities. By selecting the correct outer diameter from the available range, the plug maintains a controlled fit to support dependable cooling circuit closure.
- Port capping / unused channel closure to maintain circuit integrity
- Segment isolation for stable thermal control
- High-temperature service supported up to 150°C
Material & Process Details+
The provided specifications define the plug variant by its 150°C heat resistance, intended for cooling-circuit sealing under elevated thermal loads. However, no steel grade, exact hardness (HRC), or heat-treatment state (e.g., quenched & tempered, nitrided) is listed in the supplied data, so material microstructure details cannot be confirmed here.
From a manufacturing standpoint, cooling circuit plugs are typically produced to dimensional stability for consistent sealing performance. Because sealing reliability depends on fit and surface finish as much as bulk properties, selecting the correct outer diameter (D) is essential to avoid leakage paths.
- Heat performance: continuous suitability up to 150°C (per variant naming)
- Material/Hardness data: not specified in the input—confirm with your technical request if hardness or treatment is required for your design criteria
Sizing & Selection Guide+
Selection for this plug is primarily based on the outer diameter (D). Available sizes are 6, 8, 10, 12 mm, and you should choose the diameter that matches the receiving port or bore used in your mold cooling circuit design.
To size correctly, identify the outer diameter of the cooling circuit port where the plug will seal (often the drilled/counterbored opening or the outer seat). Then select the closest matching D from the set: 6 → 8 → 10 → 12 mm.
- Match to cavity/core requirements: ensure the plug’s D corresponds to the port’s outer diameter to maintain closure
- Fit considerations: if your port has a specific tolerance or finish requirement, verify compatibility with your machine shop’s standard tolerance class (tolerance values are not provided in the input data)
- Configurable dimension: D is variable/selected during ordering; other dimensions are not specified in the provided data
Frequently Asked Questions
Which outer diameter (D) options are available for the JWPH cooling circuit plug variant?+
The available D (outer diameter) sizes are 6, 8, 10, and 12 mm. During ordering, select the diameter that matches the receiving cooling circuit port opening in your mold or industrial manifold.
What temperature rating does this JWPH plug support for cooling circuit sealing?+
This JWPH variant is specified for 150°C heat resistance. It is intended for stable cooling circuit shutoff in environments where tooling temperatures rise during production.
How do I determine the correct plug size for an existing cooling channel port?+
Use the port’s outer diameter (the diameter of the seat/opening where the plug seals) and match it to one of the available D values: 6, 8, 10, or 12 mm. If your design uses tight tolerances or specific surface finishes, confirm compatibility because tolerance data is not included in the provided specifications.
Can this plug be used for both mold cooling circuits and industrial hydraulic/coolant circuits?+
Yes. The product description indicates use in mold cooling and also industrial fluid cooling circuit assemblies. Choose the correct D to ensure sealing fit in the specific port geometry used in each application.
Does the input data include steel grade, hardness (HRC), or heat treatment details for JWPH plugs?+
No. The supplied data only confirms the 150°C heat resistance and the D (outer diameter) options. If your application requires verification of hardness (HRC) or a specific heat treatment (e.g., nitriding or quench/temper), request the material certification or technical drawing from the supplier.
