Choose by pressure class, flange type and insulating material
Complete kit including gasket, sleeves, insulating washers and steel washers. Solves sealing and insulation problems on standard flanges while controlling stray currents.
Standard flat isolating gaskets for oil & gas service. Soft neoprene rubber factory-applied to both sides of a laminated phenolic retainer. Type E full-face and Type F ring.
China has emerged as a global hub for manufacturing excellence, combining advanced technology with competitive pricing. By partnering with Chinese manufacturers, you gain access to state-of-the-art facilities, rigorous quality control, and a vast supply chain network. Our factories leverage decades of experience producing flange insulation gasket kits tailored to meet international standards and customer-specific requirements.
The result: 30-50% cost savings compared to Western suppliers, without sacrificing quality. Every kit is dimensionally verified against ASME B16.5, ANSI, and DIN standards before shipping, and our engineering team works directly with buyers on custom specifications and material selection.
Engineered for reliability, efficiency and long service life in critical isolation service
Reliable sealing under extreme temperatures — from cryogenic service up to +80°C for phenolic, higher for G10/G11 laminate with SS core.
Dielectric strength up to 500 V/mil, protecting against galvanic corrosion and stray currents in cathodic protection systems.
G10/G11 glass-reinforced epoxy laminate and phenolic materials resist aggressive chemicals, extending equipment life.
Pre-cut kits with matched gasket, sleeves, insulating washers and steel washers — reduce installation time and labor costs.
Available in any size, material (G10, G11, phenolic, neoprene-faced), and configuration — full-face Type E, ring Type F, or SS core.
Mill Test Certificate, dimensional inspection record, and material composition report included with every shipment.
