Parker O-Ring Seals and Backup Rings - Parker Seals Suppliers

Parker O-Rings & Seals

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.

Parker O Rings


Parker O-rings are manufactured according to metric and imperial international standards such as AS 568B, DIN ISO 3601 and JIS. We utilize O-Ring compounds formulated to meet the most stringent industry standards, including FDA, USP, KTW, DVGW, BAM, WRAS (WRC), NSF, Underwriters Laboratories (UL), and Aerospace (AMS). We, the Parker O-Rings Distributors in Chennai, fulfil our customer’s demands on customer-specific requirements

Parker Back-up Rings

Back-up Rings

Parker Back-up Rings are used in combination with O-rings and are available at Arvi Hitech, the Parker Back-up Rings Distributor in Chennai . They are flat, split, spiral or contoured washer type fittings. Parker Back-up Rings are used to protect an O-Ring seal from extrusion at higher pressures and temperatures by reducing the gap on the non-pressurised side of the O-ring seal.

Parbak Back-up Ring

Parbak® Back-up Rings

Parbak® back-up rings are made from hard elastomer compounds. In combination with their profiling, plus their continuous and seamless design, this provides the O-ring with major resistance to gap extrusion. As a result, seal effectiveness and service life are improved and the application potential is extended.

Parker Piston Seals

Piston Seals

Parker Seals for hydraulic and pneumatic cylinders and actuators are designed to separate applied pressure between the piston and the rod side during the stroke movement. At Arvi Hitech, the Parker Seals Distributor in Chennai, they are available as single-acting and double acting seals in a wide range of compound and profile configurations to meet diverse Parker Sealing Solutions applications: high and low temperatures and pressures, a wide variety of media, harsh operating conditions, various friction requirements, etc. Common materials used in the Parker Seals are thermo-plastic polyurethane (TPU), polytetrafluorethylene (PTFE), polyamide (PA), and nitrile rubber (NBR). Parker piston seals can cover working temperatures from -50°C to 230°C and working pressures up to 800 bar. Some seal profiles are insensitive to extreme pressure peaks. Parker Lip Seals from Arvi Hitech, the most trusted Parker Seals Distributor in Chennai, comply with ISO 6020, ISO 5597 and ISO 7425-1 standards.

Rod Seals

Rod Seals

Parker Rod Seals for hydraulic and pneumatic cylinders and actuators seal the applied system pressure against the atmosphere side. Their purpose is to prevent external leakage and thus avoid contamination of the ambient environment. They are also available as single-acting and double acting seals. High-pressure applications usually require a tandem rod sealing system including a buffer seal. Parker Rod Seals typically interact with wiper elements in the cylinder sealing system. A wide range of compound and profile configurations is available to meet the specific application profile. There are rod seals available that comply with ISO 6020, ISO 5597 and ISO 7425-2 standards.

Rotary Seal

Rotary Seal

A rotary shaft seal is used to protect applications with a rotating shaft in wet environments. The rotary shaft seals keep lubricant (oil, grease or water) inside the application and prevents the ingress of water and dirt. There are two generic categories of Parker Rotary Seals: high-pressure/low-velocity (rotor seals) and low-pressure/high-velocity (rotary shaft seals). Both symmetrical and unsymmetrical designs are available at Arvi Hitech, the Parker Rotary Seals Distributor in Chennai. The Parker Rotary Seals outside surface are fixed to the housing, while the seal's inner lip presses against the rotating shaft. Common applications for shaft seals include motors, gear boxes, pumps and axles. They're also increasingly used for food and chemical processing, as well in pressurized gas applications.

Wiper Seal

Wiper Seal

Parker Wipers Seals are designed to prevent any contamination of the system by external particles or other environmental impacts during translatoric movements in cylinders and actuators. They also provide the static sealing function on the cylinder head versus the atmosphere. At Arvi Hitech, the Parker Wiper Seals Distributor in Chennai, the dimensions available according to DIN ISO 6195, Type E. An oversized outer diameter ensures interference fit in the groove, thus preventing ingress of foreign particles and moisture via the static seal fit of the wiper.

Guide Rings

Guide Rings

Parker Guide Rings provide the bearing function between the metallic components of the cylinder during the stroke movement and in static conditions. They prevent metallic contact between pistons and cylinders or rods and glands where forces act perpendicular to the direction of movement. The Parker Guide Rings design shows a circular, but open preform and therefore lends itself to easy assembly. The guiding tape design is endless and can be cut to any desired length. The tape is wound as a flat coil or spiral preform.
