Pressure Balancing Seal Solutions by Polypac

Overview — Reliable Pressure Balancing Seal Technology

Polypac designs and manufactures Pressure Balancing Seals engineered to stabilize pressure differentials in hydraulic and oil systems. Built on our deep expertise in filled PTFE and advanced elastomers, these seals minimize extrusion, maintain dynamic stability, and extend service life under fluctuating pressures and temperatures. Our solutions are tailored for valves, pistons, cylinders and rotary equipment that require precise pressure compensation.

Features & Benefits — Performance You Can Trust

Pressure Balancing Seals from Polypac offer controlled deformation and low friction thanks to materials such as bronze-filled PTFE, carbon-filled PTFE, MoS2-filled PTFE and glass-filled PTFE. Combined with precision-molded O-rings in NBR, FKM, EPDM, silicone and FFKM, our seals provide superior wear resistance, chemical compatibility, and leakage control. Benefits include improved cycle life, reduced maintenance, and consistent sealing under variable loads.

Materials & Customization — Engineered for Special Conditions

Polypac’s custom rubber ring and O-ring factory (10,000+ m² facility with 8,000 m² production area) offers rapid prototyping and bespoke formulations for hostile environments. We collaborate with universities and research institutes to optimize compound selection and geometry for each Pressure Balancing Seal application—whether extreme temperature, aggressive media, or tight installation space. Custom sizes, multi-lip profiles, and compound tuning are standard options.

Manufacturing & Quality Assurance — Proven Process Control

Founded in 2008, Polypac combines advanced production and testing equipment with strict QC protocols. Each Pressure Balancing Seal undergoes dimensional inspection, material certification, and performance testing to ensure reliability in high-pressure applications. Our laboratory testing replicates real-world conditions to validate leakage rates, frictional torque, and long-term durability.

Applications & Support — From Design to Delivery

Typical applications include hydraulic pumps, directional control valves, subsea actuators, and high-speed rotating shafts. Polypac provides application engineering, CAD-supported design reviews, and scalable manufacturing to meet OEM and aftermarket needs.
