Sealing Rings

Cross Manufacturing Sealing Rings are manufactured using a proprietary forging process that creates high strength and high integrity products from alloy wire or rod.

Unrivalled Size Range and Material Choice

We apply over eighty years of dedicated experience to the development, design and manufacture of metallic Sealing Rings for long term reliability in high temperature and challenging environments.
Our manufacturing capabilities encompass an unrivalled combination of materials, designs and sizes.

To meet virtually any specific application, our designs include in-springing and out-springing Sealing Rings and Ring Packs, with or without cockle springs.
Virtually any customised sectional requirements are possible.
Sealing Rings with Ø up to 79″ (2000mm) are in regular production.

High Temperature Capabilities

Our proven expertise with material choices facilitates Sealing Ring applications in temperatures of 1000°C.

We hold large stocks of aerospace standard heat resisting alloys, mostly in wire and bar form.

The list includes:
Nimonic® 75; Nimonic® 80A; Nimonic® 90; Nimonic® C.263; Inconel® 600; Inconel® 625; Inconel® 718; Inconel® X.750; Haynes® 25 (L.605); Haynes® 282; Incoloy® A.286; Waspaloy.
