This product strictly complies with the ASME B16.21 standard and is manufactured from high-quality neoprene rubber, offering excellent electrical insulation and chemical corrosion resistance. This Xiamen Neoprene Isolation Gasket is specifically designed for flange connections with a 3-inch nominal size and 150LB pressure rating. Its full-face configuration ensures uniform and reliable sealing, effectively preventing galvanic corrosion and electrolytic current. It is suitable for chemical piping, acid/alkali media, and humid environments. We also support non-standard customization, with rapid response to varying thickness, hardness, and dimensional requirements, providing a safe and durable isolation sealing solution for your piping systems. As a reliable supplier of Xiamen Neoprene Isolation Gasket, we pay close attention to every manufacturing detail, ensuring stable performance under diverse operating conditions.

I. Core Features
- High-quality neoprene rubber substrate: Combines good elasticity, weatherability, and ozone aging resistance, maintaining stable physical properties within a temperature range of -35°C to +120°C. This Xiamen Neoprene Isolation Gasket retains reliable sealing and insulation performance across a wide temperature window.

- Superior electrical insulation: Features high volume resistivity, effectively blocking electrolytic current between flanges, preventing galvanic corrosion damage to pipe base materials, and extending equipment service life. This is the key value proposition of the Neoprene Isolation Gasket in the field of insulating sealing.

- Full-face structural design: Covers the entire flange sealing surface, ensuring uniform stress distribution and moderate sealing pressure, particularly suitable for low-pressure, large-diameter, or non-metallic flange connections. This design makes the Neoprene Isolation Gasket easier to center during installation and enhances sealing reliability.

- Broad chemical resistance: Exhibits good tolerance to dilute acids, alkalis, saline solutions, oils, and various organic solvents, making it a highly cost-effective isolation material for chemical piping. By choosing the Neoprene Isolation Gasket, you can replace more expensive specialty alloy gaskets in most corrosive environments.

- Precise dimensions and strong interchangeability: With a 3-inch bore, bolt hole positioning, and thickness all executed per standard specifications, ensuring full compatibility with standard flanges. Each Xiamen Neoprene Isolation Gasket undergoes rigorous dimensional verification to guarantee trouble-free on-site installation.

II. Typical Applications
- Chemical and fine chemical piping: Used for acid/alkali transfer, intermediate pipelines, and tank nozzle flanges to block stray currents while resisting media corrosion. In such scenarios, the Xiamen Neoprene Isolation Gasket effectively isolates potential differences between dissimilar metal flanges, mitigating galvanic corrosion.

- Electroplating and electrolytic workshops: Installed at pipe connections between rectifiers and electrolytic cells in high-current environments to prevent leakage current and pitting. The high volume resistivity of the Neoprene Isolation Gasket significantly reduces stray current interference with piping systems.

- Offshore platforms and marine systems: Resistant to salt spray and humid climates, suitable for seawater cooling pipes, ballast water treatment systems, and oil/gas separation units. The adaptability of the Neoprene Isolation Gasket to salt spray and humid environments makes it a common choice for offshore engineering.

- Auxiliary media piping in food and pharmaceutical industries (non-direct food contact): Used in steam, hot water, or cleaning solution pipelines, providing clean and insulating sealing points. Even under periodic high-temperature cleaning conditions, the Neoprene Isolation Gasket maintains its structural integrity.

- Grounding isolation and cathodic protection systems: Serves as a critical component of insulating joints, ensuring accurate potential measurement and preventing loss of protective current. The Xiamen Neoprene Isolation Gasket plays a key electrical isolation role in these systems, safeguarding the authenticity of cathodic protection data.

III. Customization Services
We understand that the operating conditions of each pipeline are unique. Therefore, in addition to standard specifications, we offer comprehensive customization support:

- Dimensional customization: We can customize any nominal diameter and pressure rating according to your flange standards (ANSI/DIN/GB/JIS), with adjustable thickness. Whether for non-standard bore sizes or special pressure ratings, we can deliver the matching Xiamen Neoprene Isolation Gasket.

- Material formulation adjustment: For extreme temperatures, strong oxidizing media, or extended service life requirements, we can optimize the neoprene compound or switch to EPDM, PTFE, or composite structures. By adjusting the formulation, our Neoprene Isolation Gasket can adapt to even more demanding chemical environments.

- Non-standard bolt hole layouts: Supports multi-hole, eccentric-hole, or special flange-face opening designs. Even if your flanges are non-standard interfaces, we can customize the corresponding Xiamen Neoprene Isolation Gasket to ensure perfect bolt-hole alignment.

- Value-added testing services: We can provide dielectric strength testing, hardness (Shore A), compression set, and media immersion test reports with each shipment. Optional third-party test data are available for every batch of Xiamen Neoprene Isolation Gasket, providing a basis for quality traceability.

Our technical team offers full-process support, from selection consultation to installation guidance, ensuring that each gasket delivers optimal insulating and sealing performance in your system.
