Parker E70ORK-116 Ethylene-Propylene (EPDM) O-Ring Kit Size -116

The Parker E70ORK-116 is a precision Ethylene-Propylene (EPDM) (70 Shore A) O-ring assortment from the Parker Hannifin Seal Group, supplied in the AS568 dash -116 size (18.72 mm ID x 2.62 mm CS). Parker Hannifin is the world's largest motion and control technology company and its O-Ring Division is the global authority on elastomeric sealing, holding the original AS568 and ISO 3601 dimensional standards used by virtually every hydraulic and pneumatic OEM. The E70ORK-116 kit gives Saudi maintenance teams an immediately usable, correctly compounded set of black O-rings for sealing static and dynamic joints in hydraulic cylinders, valves, fittings and instrumentation. Razz Middle East stocks the E70ORK-116 in Jeddah, Riyadh and Dammam for 24-48 hour delivery to ARAMCO, SABIC, SWCC and NEOM project sites, eliminating the long lead times normally associated with imported genuine Parker seals.

Seal Design & Material Engineering

The E70ORK-116 is moulded from Parker's Ethylene-Propylene (EPDM) compound at a nominal hardness of 70 Shore A, the most widely specified hardness for general industrial sealing because it balances installation stretch, extrusion resistance and sealing force. EPDM provides excellent resistance to hot water, steam, glycols, brake fluids, phosphate esters, ozone and weathering, but must never be used with petroleum oils. The compound operates across a service temperature range of -45 C to +150 C, retaining its compression set resistance and elastic recovery at the upper limit so the seal continues to follow groove movement and surface imperfections. Parker controls the full vulcanisation chemistry — polymer base, cure system, plasticisers and anti-degradants — to deliver lot-to-lot consistency that generic O-rings cannot match. Every ring is checked against ISO 3601-1 grade N (general) tolerances for inside diameter, cross-section and surface finish, and against ISO 3601-3 acceptance criteria for visual defects. This matters in the Gulf, where salt-laden coastal air, UV exposure and 50 C-plus ambient temperatures accelerate elastomer ageing; a correctly compounded Parker seal delivers years of service where a sub-standard ring fails within months.

Dimensional Data & Housing Requirements

This kit covers AS568 dash size -116 with nominal dimensions of 18.72 mm ID x 2.62 mm CS. For static face-seal and radial applications, the groove should be machined to the gland dimensions published in the Parker O-Ring Handbook (ORD 5700): the groove width is sized to give 60-85% groove fill and the groove depth is set to produce the recommended squeeze of 10-30% on the cross-section, depending on whether the joint is static, reciprocating or rotary. Surface finish on the sealing faces should be 0.4-0.8 micron Ra for static seals and 0.1-0.4 micron Ra for dynamic surfaces, with lead-in chamfers to prevent shaving during assembly. Correct housing design — not the O-ring alone — determines sealing life, and Razz can supply the full groove-design tables for the -116 size.

Applications in Saudi Arabia

Across the Kingdom the E70ORK-116 is used wherever a reliable elastomeric seal is required. In Saudi Aramco upstream and downstream facilities the kit seals hydraulic actuator end-caps, valve bonnets, instrument manifolds and quick-connect couplings on workover and drilling equipment. At SABIC, Sadara and Petro Rabigh petrochemical complexes the rings seal pump housings, heat-exchanger access ports and pneumatic control valves. SWCC desalination plants rely on correctly compounded O-rings in high-pressure pump seal chambers and chemical-dosing skids, while NEOM, Red Sea Global and Riyadh infrastructure contractors use them in mobile hydraulic equipment, cranes and building-services plant. Because the E70ORK-116 ships as a single labelled assortment, plant stores can standardise on one Parker part number instead of dozens of loose sizes, cutting downtime when a seal must be replaced during a turnaround. The 70-Shore compound is matched to the dominant fluids and temperatures of each application.

Selection Guide — Temperature, Media & Pressure

Choosing the right compound is critical. Select NBR (Nitrile) for mineral hydraulic oils, diesel, greases and general industrial fluids up to about +100 C — the default and most economical choice. Select FKM (Viton) when the service involves high temperatures (up to +200 C), aggressive chemicals, fuels, or where ozone and weathering resistance is essential, such as engine, process-chemical and high-temperature hydraulic duties. Select EPDM for hot water, steam, glycol brake fluids, phosphate-ester fluids and outdoor/UV exposure, but never for mineral oils, which destroy it. Pressure capability depends on housing design and back-up rings rather than the compound alone: above ~70 bar, anti-extrusion (back-up) rings are recommended to prevent the seal extruding into the clearance gap. Razz engineers can cross-reference the E70ORK-116 against your fluid, temperature and pressure data to confirm the correct selection.
