Ferolite NAM 31 Ring Face Fibre Gaskets

Ferolite NAM 31 Ring Face Gaskets are precision-cut non-asbestos jointing seals made from aramid and mineral fibres reinforced with an NBR (nitrile) binder. They are engineered for bore-type flange sealing, offering excellent compression recovery, chemical stability, and sealing reliability in water, oil, and mild chemical services. The material is bio-soluble and food-safe, making it suitable for food, beverage, and pharmaceutical applications, though not FDA certified. NAM 31 ring gaskets deliver dependable performance under moderate pressure and temperature conditions, making them ideal for general-purpose and utility sealing in industrial operations.

FAQ – Ferolite NAM 31 Ring Face Gaskets

Q1: What makes Ferolite NAM 31 different from other non-asbestos gaskets?
A: It uses a blend of aramid and mineral fibres with NBR binder, delivering excellent flexibility and chemical stability while being bio-soluble and safe.

Q2: What is the maximum service temperature and pressure?
A: Continuous to 270 °C, short-term 400 °C, and pressure to 100 kg/cm².

Q3: Where are ring gaskets used?
A: They seal between the raised faces of flanges, ideal for steam, oil, and compressor lines where compact bore sealing is required.

Q4: Is Ferolite NAM 31 food-safe?
A: Yes – the material is non-toxic and KTW/DVGW-approved for drinking water use.
