DIN 7603 Sealing Washer

The DIN 7603 sealing washer is a ring with a small width of the working body. The product is used as a sealing element to increase the tightening force when forming a threaded fastening assembly.

It is used together with bolts, screws, self-tapping screws, studs and other fasteners that have a working shank with cut thread.

The DIN 7603 ring washer can be made of various materials.

Carbon steel, austenitic chromium-nickel alloys of classes A2 and A4, as well as non-ferrous metals and their alloys are traditionally used for its production. Products made of alloy steel are produced plain and with a protective anti-corrosion coating.

DIN 7603 Sealing Washers from the FLOK Catalogue

FLOK supplies sealing washers made of various materials.

The geometric parameters of products in accordance with the DIN 7603 standard are as follows: the outer diameter ranges from 9.9 mm to 35.9 mm, the inner diameter of the ring ranges from 6.2 mm to 30.0 mm, and the flange width is 3.7-5.9 mm respectively. The washer thickness is small, only 1-1.5-2 mm.

The small thickness and flange width of the washers help eliminate gaps in the fastening assembly, making the joint stronger, more airtight and reliable. Sealing washers and other elements of a specific fastening assembly must be made of identical materials and match each other in size.

DIN 7603 sealing washers can be selected on the website according to specified characteristics using the filter in the catalogue.
