【MY Packing】 A packing that can be used as a low-pressure lot seal and piston for hydraulic and pneumatic equipment. It is designed to accommodate the groove dimensions of the O-ring P series, so it can be changed from an O-ring. MY Packing has low sliding resistance, and the basic material is Type A. 【RMY Packing】 A relatively larger size packing used for similar applications as MY Packing. The basic material is NBR 80 degrees, which has better pressure resistance than MY Packing. For specifications and details, please download the catalog.

This is a feeding method that allows the production of O-rings in the required sizes without dedicated molds. Since it can be manufactured using vulcanization for items with an inner diameter of Φ300 or more, large-diameter O-rings in small lot sizes can be produced with short lead times and low costs. We have a wide range of molds for O-ring thicknesses from Φ3 to Φ20, so we can respond to urgent requests. Additionally, because of the vulcanization method used for the joint, there is no reduction in joint strength, and dimensional accuracy is stable due to compression molding with molds. (Round type, dome-shaped packing, O-rings, dome-shaped packing, square rings) *An O-ring is a ring-shaped packing with a circular cross-section (O shape) that is generally installed in a groove and moderately compressed to be used as a seal for a wide variety of fluids, such as oils, water, chemicals, and gases like air.
