An O-ring is the cheapest part in a hydraulic system and the most common cause of failure. Parker's sealing and shielding portfolio combines material science with manufacturing precision - and is backed by the industry's deepest fluid compatibility database.
Parker O-Rings (NBR, FKM, EPDM, FFKM, silicone)
Parker O-rings are elements with circular cross-sections, mainly used in static applications to prevent the leaking of fluids and gases. The sizes are specified by the inside diameter and the cross-section diameter. O-rings are very commonly found in pumps, cylinders, connectors and valves, helping to seal joins between separate parts. Due to its many applications, there is also a wide variety of O-ring material choices available at Arvi Hitech, a leading Parker O Rings Distributor in Chennai. Nitrile (Buna), Neoprene, Ethylene Propylene (EPDM Rubber), Silicone, Fluorocarbon (Viton), and PTFE (Teflon) are among the most commonly used compounds for O-rings and seals. The installation is simple, and replacements are very easy.

Why Specify Parker Sealing & Shielding
Material database depth
Parker's inPHorm® selection software and chemical compatibility data covers thousands of fluids - eliminate guesswork on FKM vs NBR vs FFKM.
Compound traceability
Every Parker compound has a documented data sheet - temperature range, hardness, certifications - for design files and audits.
FDA, USP Class VI, 3-A
Parker offers food-, pharma-, and dairy-grade compounds where regulatory traceability is non-negotiable.
EMI & thermal management
Parker Chomerics shielding gaskets and thermal interface materials for electronics, telecom, defence, and EV applications.
Lower failure rate
Genuine Parker seals reduce field failures versus generic alternatives - a meaningful TCO benefit when seal replacement requires equipment teardown.

Frequently Asked Questions
NBR (nitrile) suits petroleum-based hydraulic oils up to 100°C. FKM (Viton) handles aggressive chemicals and temperatures up to 200°C. EPDM is preferred for hot water, steam, and brake fluids but is incompatible with petroleum oils. Our team can run a full compatibility check using Parker's inPHorm® software.
Yes. We supply Parker compounds certified to FDA 21 CFR 177.2600, USP Class VI, 3-A Sanitary Standards, and EU 1935/2004 - used in food contact, pharmaceutical, and biotech applications.
Yes. Parker offers custom seal design and manufacturing - including profile design, tooling, and small-batch production - for applications where standard O-rings or seals are not optimal.
Parker Chomerics EMI shielding gaskets, conductive elastomers, and absorber materials prevent electromagnetic interference in electronics enclosures, telecom equipment, defence systems, and electric vehicle components.
