Edge-bonded engineered seals

These type of seals use the metal frame to create an artificial, one-sided groove on the sealing surface.  The metal frame positions the rubber sealing element on the desired seal path and it provides a permanent load path once the system is bolted down.  This way, the rubber is optimally squeezed and once the bolts have been tightened, the metal load path will make subsequent re-torquing unnecessary.  

Edge-bonded seals are generally used in higher volume applications since the metal can be cost effectively manufactured by stamping.  The metal-rubber bond can be achieved mechanically and/or chemically and they can be designed in a variety of metal and rubber combinations.   

Groove-Bonded Engineered Seals

These type of seals use a metal plate machined with ports for the fluids to flow through and grooves into which the rubber sealing element is bonded and molded.  The rubber seal configuration maximizes sealing performance while the metal plate positions the seals in optimal locations and provides a torque retention path for the system being sealed.

Groove-bonded seals are used in high demand applications where extreme pressures and/or media demands must be considered.  The machined  grooves of this design protect and reinforce the rubber and allow for one-sided or dual-sided seal plates.  As with all our products, a multitude of metal, metal finish and rubber combinations are available.    

Face-Bonded Sealing Products

These type of products are designed and manufactured for a multitude of purposes.  They can be stand-alone sealing elements such as poppets or be designed in conjunction with edge or groove bonded seals.  Face-bonded seals are often used to seal against delicate surfaces such as glass, crystal and ceramics.  They are also used in sealing applications where the seal is mechanically activated by a spring, a solenoid or a similar device.
