Novel compound has many sealing uses
A new HNBR compound developed by the Parker Seal Group is suitable for applications in both water and gas.
O-rings with the elastomer resin coating are approved for use with drinking water treatment, storage and distribution processes.
They can be used in threaded connectors, valves, fittings and meters in plumbing, heating and water supply technology applications.
Unlike surfaces treated with oils or greases, Parcoat KTW seals do not contaminate the conveyor and feeder systems of automatic assembly lines.
The rings will neither stick together nor be prone to damage, and they can be elongated by up to 150% without the transparent antifriction coating bursting or breaking.
The installation process can be repeated several times using the same assembly forces.
Parcoat KTW is temperature-resistant from -40 to +120C.
Under the brand name of Parcoat KTW Parker offers O-rings made from NBR, HNBR, EPDM, FKM, MVQ and FVMQ compounds.
For drinking water applications, O-rings made from EPDM are primarily used. Request a free brochure from Parker Hannifin Seal Group Europe ...
