JMR Type Color Marker Rings for Water Flow Checkers

Q: Which inner diameter variant should I choose for a water-flow checker labeled with the JMR marker ring?

Choose based on the marker ring inner diameter: d = 10 mm , 12 mm , or 17 mm . Match d to the required seating fit on your water-flow checker assembly. Since tolerances are not provided, verify fit against your component drawing before final installation.

Q: Can I use different colors (B/G/K/R) to standardize flow circuit identification across multiple molds?

Yes. The available color codes are B (Blue) , G (Green) , K (Black) , and R (Red) . Use the same color scheme across molds to keep maintenance and inspection workflows consistent, especially when multiple cooling/manifold branches are present.

JMR Type color marker rings for water flow checkers are designed to provide clear identification in industrial piping and checking systems. These marker rings improve workflow organization while supporting dependable long-term use in production environments.

Product Guide

🏭Application Scenarios+

In injection mold tooling, marker rings like these are used to keep water-flow checking components correctly identified during installation, commissioning, and ongoing maintenance. They are typically installed on hoses, fittings, or checking units associated with cooling/heating circuits to support rapid identification during troubleshooting.

Automotive mold water-flow checkers: Use color-coded JMR marker rings (Blue/Green/Black/Red) to visually distinguish branches or stations, reducing downtime when verifying flow balance after production shifts.
Medical and precision molding manifolds: Apply the appropriate inner diameter so the ring seats consistently on the checking component, helping technicians maintain correct routing without needing to trace lines.
Large die-casting tooling refurbishment: During maintenance cycles, the durable, long-life marking simplifies cable/component sorting and minimizes rework caused by misidentification.

The available inner diameters (d = 10, 12, 17 mm) and multiple colors make this variant suited for practical, repeatable labeling across different standard setups.

🔧Material & Process Details+

The provided specifications specify the JMR type color marker rings and their inner diameter and color options, but no steel grade or heat-treatment details are included. As a result, material hardness, wear resistance, and heat treatment state (e.g., quenched & tempered, nitrided) cannot be stated from the supplied data.

For mold tooling applications, selection should focus on dimensional compatibility (matching d = 10 / 12 / 17 mm) and color identification scheme (B, G, K, R) to ensure stable seating and legible labeling over maintenance intervals.

Hardness/wear trade-off: Not specified in the data, so engineers should confirm the actual polymer/insert material and durability level with the supplier before use in high-abrasion environments.
Heat treatment: Not applicable or not specified for this item based on the provided metadata.

📐Sizing & Selection Guide+

Select the marker ring using the inner diameter d specified for your water-flow checker component. The product offers d = 10, 12, or 17 mm; choose the smallest diameter that correctly fits your target component so the ring seats securely without excessive looseness.

Match to cavity/component requirements: Identify the checker’s outer feature or required seating bore from your assembly drawing, then select the ring with the closest d to achieve consistent placement.
Fit and tolerance considerations: Because no tolerance values are provided in the data, confirm fit using your drawings and any internal standard allowances for the specific water-flow checker design.
Color selection: Pick B (Blue), G (Green), K (Black), or R (Red) to align with your shop’s labeling conventions for flow identification and maintenance records.

Dimensions are configurable by variant (d and color). No other length/width parameters are provided, so sizing should be verified against the mating component geometry using the d criterion.

Frequently Asked Questions

Which inner diameter variant should I choose for a water-flow checker labeled with the JMR marker ring?+

Choose based on the marker ring inner diameter: d = 10 mm, 12 mm, or 17 mm. Match d to the required seating fit on your water-flow checker assembly. Since tolerances are not provided, verify fit against your component drawing before final installation.

Can I use different colors (B/G/K/R) to standardize flow circuit identification across multiple molds?+

Yes. The available color codes are B (Blue), G (Green), K (Black), and R (Red). Use the same color scheme across molds to keep maintenance and inspection workflows consistent, especially when multiple cooling/manifold branches are present.

What material or heat-treatment properties are specified for these marker rings?+

The supplied product data does not include a material grade, hardness value (HRC), or any heat-treatment condition. Therefore, wear resistance and toughness trade-offs cannot be stated from the given specifications. Confirm the actual construction material with the supplier for high-temperature or abrasive applications.

Are the JMR marker rings a fixed size or configurable by variant?+

Sizing is variant-based. The product is offered with configurable inner diameter d values (10, 12, 17 mm) and selectable colors (B/G/K/R). No additional dimensional parameters (such as length/width) are provided in the input data.

Will selecting the closest d value always ensure a stable seated marker ring during maintenance?+

Not necessarily. The dataset provides d values but does not list tolerances or the exact seating interface geometry. Use the d selection as the first step, then confirm seating stability using your assembly drawings and any internal fit allowances.
