Pressure Plug Steel Inch Taper Plug

Pressure plug components are used to close and seal pressure ports inside injection molds where the cooling or fluid circuit needs controlled pressure and leak-tight shutoff. This steel-inch taper plug variant is intended for steel-inch taper plug applications and targets a flush-type 7/8" taper interface to support consistent installation fit and reliable sealing at the plug seat.

• Industrial fluid and tooling manifolds: Use the tapered pressure plug to cap ports after circuit testing, helping maintain pressure during leak checks and production runs.
• Internal cooling/heating circuit closures: Seal pressure interfaces in mold interior plumbing where surface flush fit reduces interference with adjacent components and tooling features.
• Packaged maintenance and kitting: The inch packaged availability supports faster replacement planning for lines requiring nominal pipe sizes within the provided range.

Its packaged inch sizing and taper fit standard make it suitable for shops that build or service molds using inch-based internal cooling and pressure port systems.

The provided specifications describe a steel pressure plug for steel-inch taper plug applications; however, no specific steel grade, hardness (HRC), or heat-treatment state is listed in the product data. As a result, hardness, wear-resistance performance, and tempering/nitriding details cannot be confirmed from the supplied information.

• Material role: Steel construction is selected for dimensional stability and durability in pressurized interfaces.
• Heat treatment: The product data does not specify whether the plug is pre-hardened, quenched & tempered, or treated (e.g., nitrided).
• Trade-offs: Without confirmed grade and HRC, toughness vs. wear-resistance cannot be stated for this exact variant.

If you need a hardness target for sealing wear or galling risk, provide the intended duty (pressure, cycle count, coolant/fluids, and port geometry) so a grade/heat-treatment recommendation can be validated.

Select the correct plug size by matching the Nominal Pipe Size (in) and ensuring the taper interface conforms to the steel-inch taper plug standard referenced by this component. The specification lists Nominal Pipe Size (in): 1 ~ 3, and the plug is supplied in packaged inch sizes to support kitting for maintenance and builds.

• Match port nominal size: Choose the plug nominal pipe size within 1 to 3 inches that corresponds to the pressure port/seat in the mold plumbing.
• Verify taper fit: This variant is identified as a flush-type 7/8" taper plug design; confirm the mating bore/seat geometry uses the same taper standard for a flush interface.
• Tolerance and fit: No explicit tolerance values are provided. Plan installation by checking fit during assembly and follow your standard practices for sealing performance on tapered seats.

If your cavity/core pressure port is sized using a different nominal basis, use the matching packaged inch size to avoid under- or over-seat contact at assembly.
