Thanks to the symmetrical profile, they can act as both a rod seal and a piston seal.<\/p>\n<h3><strong>Rotary seals<\/strong><\/h3>\n<p>Used to seal assemblies with rotating shafts.

This is significantly faster than waiting for moulded products to be delivered from abroad.<\/li>\n<li>Custom sizes and materials. You can always choose the material for your seals according to the technical requirements of your hydraulic cylinder or other hydraulic mechanism.<\/li>\n<li>Orders from 1 piece, since not all suppliers allow you to order a single seal.<\/li>\n<\/ul>\n<p>You can find more detailed information about seals, and download a catalogue with the main profiles and technical specifications, in the section <a href=\"https:\/\/nak.ua\/uk\/gidravlichni-ushhilnennya\/\">&#8220;Hydraulic seals&#8221;<\/a>.
