CoRE FEATURES

Designed for Reliable Stuffing Box Sealing

Precision Die-Moulded Construction

Exact dimensions ensure uniform density and proper stuffing box fit.

Improved Sealing Integrity

Dense structure reduces leakage versus braided packing.

Ready-to-Install Rings

Preformed rings enable fast, error-free installation.

Material-Optimized Performance

Multiple materials suit pressure, temperature, and media demands.

Product information

Configured for Stuffing Box Sealing

PG Die-Moulded Rings are engineered to deliver consistent sealing, controlled leakage, and extended equipment life across demanding industrial environments.

Types

Graphite Die-Moulded Rings

Expanded flexible graphite pressed into high-density rings for high-temperature and chemical-resistant sealing.

PTFE Die-Moulded Rings

Manufactured from virgin or filled PTFE, offering exceptional chemical resistance, low friction, and non-stick performance for corrosive and hygienic services.

Carbon Die-Moulded Rings

Produced from carbonized materials for high strength, good thermal conductivity, and reliable performance in aggressive fluids and high-speed applications.

Aramid Rings

Preformed from aramid or high-strength synthetic fibers, delivering excellent abrasion resistance for slurries and high-pressure pump services.

Hybrid / Combination Rings

Engineered combinations of materials designed for specialized stuffing box arrangements, balancing sealing efficiency and abrasion resistance.
Benefits
01

Leakage Control

Maintains controlled sealing under pressure, reducing fluid loss and emissions.

02

Thermal Tolerance

Performs reliably across wide temperature ranges in dynamic services.

03

Low Shaft Wear

Optimized structure minimizes friction and protects shafts and sleeves during operation.

04

Service Longevity

Resists compression fatigue, ensuring consistent sealing performance over extended service.
