Oil Resistance: NBR material provides good resistance to many mineral oils, lubricants, and fuels.
Fabric Reinforcement: Optional fabric layers help improve strength and dimensional stability.
Flexible Performance: Designed to withstand repeated movement and pressure changes.
Custom Design: Available in different shapes, thicknesses, diameters, and mounting configurations.
OEM & ODM Service: Custom manufacturing based on drawings, samples, or technical specifications.
JINNAI SEAL manufactures custom rubber diaphragms for industrial pumps, pulse valves, pressure regulators, and fluid control equipment. Made from NBR (Nitrile Butadiene Rubber), these diaphragms offer good resistance to oils and fuels, making them suitable for various oil-contact applications.
Fabric-reinforced construction is available to improve dimensional stability, tensile strength, and resistance to repeated flexing. The molded diaphragm design features a flexible sealing surface and reinforced outer sealing area to support reliable operation in demanding equipment.
JINNAI SEAL rubber valve diaphragms are made from high-quality elastic rubber materials and designed to fit tightly against the valve seat, creating a reliable face seal. Their elasticity helps maintain effective sealing even under low-pressure conditions, reducing the risk of leakage and ensuring stable, safe valve operation.
The diaphragms can operate at temperatures up to 80°C, with the actual temperature range depending on the rubber material and compound. We offer custom options in various sizes, thicknesses, shapes, and materials to meet the requirements of different valves and industrial fluid control systems.
JINNAI SEAL supports customized rubber diaphragm production according to customer drawings, samples, or application requirements. Material, hardness, thickness, diameter, shape, fabric reinforcement, and mounting details can be tailored to specific operating conditions.
JINNAI SEAL specializes in custom rubber parts in various shapes, sizes, and materials. We provide custom rubber components, molded rubber products, rubber seals, gaskets, and diaphragms tailored to your drawings, samples, and application requirements. OEM and ODM services are available.
