Enerseal® Spring Energized Seals

Face seals Enerseal® internal pressure

Spring Energized Seals Enerseal®, custom and standard dimensions available. Jacket in PTFE compound, PEEK, UHMW-PE, PU 54Sh.D. Jackets and electro-welded springs are designed and realized within the company, so that HD has the complete control of the production process. Spring are available in Aisi302, Elgiloy, Hastelloy and NACE approved Inconel X750.
For the "V" shaped cross sections up a max. D diameter  of 250,  an optional EU-FDA approved silicone filling is available.
