CoRE FEATURES

Optimized for Utility Performance

Composite Construction

Metal core with moulded elastomer sealing.

Non-Bonded Design

Mechanically moulded rubber improves sealing resilience.

Service-Specific Elastomers

EPDM and Viton options for varied media.

WRAS / KTW Approved Options

Certified grades for potable water applications.

Product information

Configured for Utility & Process Applications

Engineered composite gasket profiles designed to suit varying flange loads, pressure conditions, and alignment requirements across water, wastewater, and general industrial piping systems.

Types

Flat Rubber Steel Gasket

Simple flat profile for standard flanged connections in medium-pressure industrial and utility applications.

O-Ring Profile Gasket

Pressure-energized design improving sealing efficiency for higher-pressure API flange systems.

O-Wing High-Pressure Gasket

Wing or lip-shaped sealing profile for high-pressure systems, supplied with outer guide ring for flange alignment.
Benefits
01

Low Load

Maintains effective sealing under lower bolt loads, suitable for delicate or glass-lined flanges.

02

Flange Fit

Soft elastomer outer layer compensates for surface irregularities and minor misalignment.

03

Vibe Control

Absorbs movement and mechanical vibration in pumps, compressors, and rotating equipment.

04

Heat Range

Machined precisely to match ASME and API groove tolerances for dependable sealing.
