Injection Mold Water Plug D8 (15PCS) Adjustable Threadless Design for Mold Cooling System Reusable Durable

Water Plug D8 (15 pcs) Compact metal water plug designed for plastic molds and cooling or heating pipelines. Provides adjustable, reusable sealing without tapping or external sealing tape, and is suitable for thermal conductivity systems in molding and fluid circulation applications. Key benefits Fast, tool installation: inserts quickly without tapping and can be repositioned as needed. Adjustable sealing: springloaded design with an Oring and tapered profile lets you set tightness without extra sealing materials. Durable and corrosionresistant: metal construction built for repeated use in normal and temperature environments. Flexible placement: can be used anywhere along water pipelines or inside mold channels for targeted sealing. Main features Design uses a tapered profile, an Oring, and a spring piece to create a secure, adjustable seal. No tapping required and no need for waterstop belt or tape. Can be loosened, repositioned, and pulled out with a water nozzle jet if not seated correctly. Suitable for both cooling and heating circuits where thermal conductivity is required.

For example, use an 8.1 mm hole for an 8 mm plug. If the plug is not fully seated in a pipeline, loosen it and use a nozzle jet to pull and reposition. Suitable for placement at any position along water or heating pipelines and inside mold cooling channels. Typical applications Injection molding: seal and control cooling channels in plastic molds for targeted temperature management. Machine cooling circuits: block or redirect water flow during maintenance or modification of cooling lines. Heating systems and thermal conductivity setups: temporary or adjustable sealing in heating loops and thermal transfer piping. This water plug provides a practical, adjustable sealing solution for molds and pipeline systems where quick installation, repositioning, and reliable sealing performance are required.
