Product Description

The rubber joint adopts premium EPDM rubber, strictly tested for color properties, volatiles, vulcanization, and other essential characteristics to ensure zero defects from the source.

Our flanges meet rigorous international standards including DIN, ANSI, ASME, JIS, BS, and EN. We maintain extremely high accuracy in thickness, surface smoothness, and caliber precision.

The reinforcing ring consists of high-quality metal wire wrapped within the rubber, effectively enhancing the tensile and pressure resistance of the port.
