"O" type Seal ring HN 7445-75.5x3.55
This "O" type seal ring, referenced as HN 7445-75.5x3.55, is a precision elastomeric component designed for hydraulic and sealing applications within power station equipment. The designation indicates an inner diameter of 75.5 mm and a cross-section width of 3.55 mm, conforming to standard metric O-ring sizing. Deyang Dongfang Yoyik Engineering Co., Ltd., based in Sichuan, China, supplies this component for use in systems such as hydraulic control check valves, circulating valve pistons, and other fluid power assemblies common in power generation infrastructure.
The seal ring is listed alongside a range of related YOYIK products for power station maintenance, including solenoid valves, pump couplings, and accumulator bladders. Buyers should confirm the specific elastomer compound (e.g., Nitrile, Viton, EPDM) and temperature rating directly with the supplier, as these details are not specified in the current listing. The HN 7445 reference suggests it may be designed for high-pressure hydraulic service, but technical datasheets should be requested to verify compatibility with your operating media and conditions.

Sourcing "O" type Seal Rings from Deyang Dongfang Yoyik Engineering Co., Ltd. - Import Guidance
When sourcing the HN 7445-75.5x3.55 seal ring from Deyang Dongfang Yoyik Engineering Co., Ltd. in Sichuan, China, begin by requesting a detailed technical datasheet. This should confirm the elastomer material, hardness (Shore A), pressure rating, and temperature range. For hydraulic applications in power stations, material compatibility with your operating fluid (e.g., mineral oil, phosphate ester) is critical. Ask the supplier to specify whether the ring meets any particular international standards for dimension or material.
Establish clear trade terms before placing an order. Confirm the Incoterms (e.g., FOB, CIF, EXW), payment methods, and packaging details to ensure the seals arrive undamaged. Since YOYIK is a manufacturer-integrated supplier based in Deyang, discuss whether they can provide custom sizes or materials if the standard HN 7445 specification does not perfectly match your application. For project-critical components, consider requesting a sample batch for testing and validation before committing to a bulk purchase.
Coordinate logistics with your freight forwarder, noting that Deyang is inland in Sichuan Province. The nearest major port for international shipment is typically Chongqing or Shanghai. Factor inland transport time into your delivery schedule. For ongoing maintenance projects, discuss the possibility of a framework agreement for regular supply of seals and related components like solenoid valves and pump parts to streamline procurement.
