Wiper Seals

Wipers are in fact the front line of defense in the case of a Sealing System, keeping the contamination out. Some designs of the Wiper have a dual role, apart from keeping the contamination out; they also support the Rod Seals by providing a Barrier for the Oil, Assisting the Back Pumping of Oil into the System. Triada offers a wide range of Wipers, suiting to different applications be it in Mines, Water, Snow, Indoor, Furnaces & Chemical Surroundings, Dusty Environment etc.

Note: Kindly contact Application Engineering Team @ Triada Technologies, who will be delighted to assist you in selecting the most appropriate seal design, material etc, for your application.
