For o rings and rubber parts, We generally pack by hard cartons and total by wooden pallets. For o ring kits, We pack by strong cartons and outside by carton belts, Pallets packing are also available.
-
All rubber products formulas are according to customers’ technical property requirements and 100% inspected by smart automatic optical inspection machines.
-
We have more than 10000 sets o ring molds including popular AS568, metric, JIS, BS standards. Most sizes we have stocks and we accept small batch of orders.
-
Generally we accept 30% T/T in advance, Balance before shipment or againt B/L copy. L/C or T/T after shipment can be discussed too.
-

-
Silicone O-Rings compliant with FDA standards are recommended for food processing, beverage, and medical applications due to their chemical resistance and sterilization compatibility.
-
Yes, using FKM/Viton or NBR materials, O-Rings can withstand high-pressure and high-temperature environments depending on the selected material and application.
-
Each standard (AS568, JIS, Metric) defines its own tolerances for ID, OD, and CS. Refer to the corresponding specification chart for precise tolerances.
-
Yes, you can provide required inner diameter (ID), cross-section (CS), outer diameter (OD), material, and quantity. Custom O-Rings can be manufactured according to your specifications.
-
Consider operating temperature, chemical exposure, pressure, and compliance requirements. NBR is good for oils and hydraulic fluids, FKM/Viton for high temperature and chemical resistance, EPDM for outdoor or weathering conditions, and Silicone for food/medical applications.
-
AS568 uses Imperial sizing standard, JIS follows Japanese standards, and Metric uses millimeter units. Each standard provides precise dimensions and tolerances for different industrial applications.
