An innovative filter cartridge adapter for sealing cartridge filters into 222- and 226-style filter housings.
The nO-Ring® seal is an innovative adapter for sealing cartridge filters into 222- and 226-style filter housings. The patented nO-Ring® design provides the security of a double O-ring seal without the use of elastomeric O-rings. This seal is ideal for use in critical pharmaceutical, semiconductor, and chemical applications, which would otherwise require the use of expensive, fluoropolymeric or perfluoroelastomeric O-rings. Typical applications include filtration of high purity chemicals, such as ultrapure and DI water, acids, bases, solvents, photochemicals, developers, etchants, and rinses.
The patented nO-Ring® design eliminates the need to select and use expensive, chemically resistant O-rings for aggressive chemical or solvent applications. This reduces material costs for each batch or process line. By eliminating the extra O-ring materials, total filter extractables are reduced. Filter installation and removal concerns associated with O-ring durometer and/or deterioration in service are also eliminated.
Design Features
- All-polypropylene construction provides wide chemical compatibility while reducing total filter extractables
- Unique adapter design easily distinguishes nO-Ring® cartridges from other cartridges, which may have identically colored and textured o-rings but differing chemical compatibilities
- Media options include: STyLUX® or EverLUX® PES, SteriLUX® or Steridyne® PVDF, Ultradyne® PTFE; ALpHA® and Vangard® PP microfiber, Protec® glass microfiber, DeltaMax® and DeltaDepth® PP depth media

Frequently Asked Questions
What is the nO-Ring® Filter Cartridge Adapter?
The nO-Ring® Filter Cartridge Adapter is a patented O-ring-less sealing adapter designed to seal cartridge filters into 222- and 226-style filter housings. It provides the security of a double O-ring seal without using elastomeric O-rings, reducing material costs and extractables. Constructed entirely of polypropylene, it offers wide chemical compatibility and is ideal for critical pharmaceutical, semiconductor, and chemical filtration applications.
What applications is the nO-Ring® Filter Cartridge Adapter used for?
The nO-Ring® Filter Cartridge Adapter is used in critical pharmaceutical, semiconductor, and chemical applications. Typical uses include filtration of high purity chemicals such as deionized water, acids, bases, solvents, photochemicals, developers, etchants, and rinses. Its chemical resistance and O-ring-less design make it suitable for aggressive chemical or solvent filtration processes.
What specifications or sizes are available for the nO-Ring® Filter Cartridge Adapter?
The nO-Ring® Filter Cartridge Adapter is available for 222- and 226-style filter cartridges with nominal cartridge lengths of 10″, 20″, 30″, and 40″ (25 cm, 50 cm, 75 cm, 100 cm). It supports filtration ratings from 0.04 µmºm to 99 µmºm. Maximum operating differentials are 80 psi at 100 ¬∞F, 60 psi at 150 ¬∞F, and 30 psi at 180 ¬∞F. The adapter is constructed entirely of polypropylene with thermal bonding sealing.
What makes the nO-Ring® Filter Cartridge Adapter unique?
The nO-Ring® Filter Cartridge Adapter is unique because it eliminates the need for elastomeric O-rings by using a patented O-ring-less sealing design that provides the security of a double O-ring seal. This reduces material costs, lowers total filter extractables, and removes concerns related to O-ring deterioration or durometer changes. Its all-polypropylene construction offers wide chemical compatibility and easy identification from other cartridges with similar colored O-rings.
What other products are commonly used with the nO-Ring® Filter Cartridge Adapter?
Commonly used complementary products with the nO-Ring® Filter Cartridge Adapter include upstream single-use systems and tubing such as Single-Use Systems, M-Flex® TPE Tubing, M-Sil™ Braid Reinforced Silicone Tubing, and BioLink® Modular Overmolding Technology. Downstream accessories like the SGT (Single-Use Gauge Tee) are also commonly integrated.
