Neoprene Faced Phenolic Gaskets – precision-engineered flange isolation gaskets combining a soft neoprene sealing face with a rigid phenolic core. Trusted by oil & gas, petrochemical, and power generation industries for cathodic protection and electrical isolation. As a leading China phenolic gasket manufacturer, Kaxite delivers custom sizes, Type E (full face) and Type F (ring) configurations, with full material traceability and fast global shipping.
Neoprene Faced Phenolic Gaskets are high-performance flange sealing components manufactured by factory-bonding a soft neoprene rubber layer to both sides of a rigid phenolic laminate retainer. This construction provides an effective sealing surface that conforms to flange irregularities while maintaining dielectric isolation. Widely used in oil and gas pipelines, petrochemical plants, and power generation facilities, these gaskets prevent galvanic corrosion, eliminate stray current hazards, and ensure cathodic protection system integrity. As a premier China Neoprene Faced Phenolic Gaskets supplier, Kaxite offers both standard and custom-engineered solutions to meet diverse industrial requirements.
The combination of neoprene's resilience and phenolic's structural strength delivers reliable sealing under temperatures up to +79°C and pressures exceeding 25,000 psi compressive strength. With dielectric strength of 500 Volts/Mil and low water absorption (1.6%), these gaskets provide long-term isolation in demanding environments. Available in Type E (Full Face) and Type F (Ring) configurations, our gaskets are precision-cut to fit ANSI, DIN, JIS, and other flange standards.

As an ISO 9001:2015 certified China Neoprene Faced Phenolic Gaskets supplier, Kaxite ensures stringent quality control at every production stage:
Case Example: Offshore Platform Cathodic Protection
A major offshore oil operator in the North Sea experienced electrical shorting issues due to degraded rubber gaskets in their cathodic protection system, leading to accelerated pipeline corrosion. Kaxite supplied Neoprene Faced Phenolic Gaskets in Type E (full face) configuration with custom thickness. After installation, dielectric resistance testing confirmed complete isolation, and the gaskets have performed without failure for over 18 months, eliminating corrosion-related downtime and saving an estimated $120,000 annually in maintenance costs.
