Metal Jacket

Solid design - Solid Results

Metal jacket gaskets are the most basic type of semi-metallic gasket combining the high pressure suitability and blow-out resistance of metallic materials with the improved compressibility of soft materials.

Corrugated Metal

Graphite Coated

CMGC gaskets featuring a corrugated metal core with a highly compressible graphite overlay, delivering a reliable gasket with the ability to seal at low bolt loads, conform to minor flange imperfections and be manufactured in virtually any configuration.

Enviroflex

Spiral Wound Gasket

Spiral Wound gaskets consist of metal strips spirally wound with a soft sealing filler material. This sealing element is assembled with or without a metallic centering and/or inner ring(s). Made to t #150 to #2500 pipe class flanges, they can be custom-made in various alloys and fillers to meet your requirement, custom sizes and application.

Enviroflex MGM

Spiral Wound Gasket

Designed to outperform standard graphite-filled gaskets in oxidizing environments, the Enviroflex MGM is a perfect match for exhaust manifolds, catalytic converter processes and steam applications. Available in winding and ring material combinations to suit your application needs

Maxiprofile

Semi-Metallic Gasket

The Maxiprofile is a composite gasket that utilizes a serrated metal core with a soft facing material. The metal core is machined on each contact face with concentric serrations providing high pressure areas and ensuring that the soft coating flows into any imperfections in the flange even at relatively low bolt loads.

Ring Joint

Metallic Ring Joint Gasket

Metallic ring joint gaskets are heavy duty, high-pressure gaskets largely used in off¬shore petrochemical applications. These precision-engineered components designed for use in conjunction with precision-machined flanges are manufactured in accordance with ASME B16.20 and API 6A.

Special Alloy Gasket Materials

Exotic Metals

For harsh environments, special alloy gaskets are required. We can manufacture semi-metallic gaskets (spiral wound, serrated gaskets, etc.)

Klinger Maxiflex pro-X

Seawater Applications

Designed for use in seawater applications where the graphite cannot be exposed to the media. Maxiflex PRO-X incorporates a serrated PTFE faced inner ring which seals with very low load. This offers exceptional sealing performance at the gasket bore to reduce crevice corrosion at the inner ring.

Safeguard KFSCCG

Klinger Fire Safe Corrosion Control Gasket

Regular corrosion inspection activities can be completed with the knowledge that joints can be remade even if corroded flanges are evident. This is facilitated with the Klinger FSCCG without the need for expensive and disruptive flange replacement or machining.

Klinger Sentry Gasket

Maxiprofile & RTJ

— Allows leak testing on individual flange joints without the need to pressurize the full system.
— Leak test both the primary and secondary sides of the seal.
— Speeds up the leakage testing reducing plant downtime.
— Significantly reduces the volume of testing media required.
— Validates individual joint integrity at installation reducing
the need to re-visit the joint.
— Joints can be tested and adjusted if leakage occurs, in one visit to the flange.

Ring type joints are precision engineered components designed to be used with precision-machined flanges. The ring gasket is located within annular recesses in the opposing faces of the flanges. The ring gasket is compressed into the groove and the angled sealing faces deform to match the grooves and create a seal.

Maxiprofile gaskets can also be manufactured from a range of core materials according to media compatibility and temperature considerations.

The metal core is machined on each contact face with concentric serrations which provide high pressure areas, ensuring that the soft coating flows into any imperfections in the flange even at relatively low bolt loads. The result is a gasket which combines the benefits of soft, cut materials with the advantages of seal integrity associated with metallic gaskets.
