A seal for every filtration use case

Filter housings and replaceable elements utilize static and semi static seal designs configured in face seal, radial seal, piston seal or bore seal applications and include specialty vent seals, lathe cuts, square cuts, square seals, primer seals, flow control and backflow prevention seals, lip seals and u-cups.  There is a specialty filter for every industrial application, from food and beverage through biopharma, high purity gas, hydraulics, fuels, CCV (crank case ventilation, and sanitary systems).  Elements are paper, porous membrane, porous plastics, meshes and so on.  While each filter is optimized for its intended use, the seal profiles and materials have to work with the intended media while maintaining acceptable long term compression set resistance, permeation performance, purity, and optimal interference fit for predictable installation/filter change out.


Quality at the core

Quality comes first with Darcoid.  Nothing moves without the Quality seal of approval.  Our team is driven to assure zero defects with control plans aligned to your supplier quality manual . We secured ISO 9001 registration in 2002 and we continue to maintain ISO 9001:2015 standards. We most recently achieved certification to the IATF 16949:2016 standard in 2021.  We recognize specific QA and regulatory requirements for filtration industry applications.  We take care to understand critical control features based on the application and include those in our PPAP control processes.  If you are at all uncertain of your current seal supplier’s commitment to quality, take our five question quality quiz for a pulse check and to benchmark with your peers.   

If you are dealing with recurring quality escapes please contact us and book time with our Quality Manager. Our QA team has developed a wealth of seal quality expertise over the years.  We know where and how escapes can happen at every step of the manufacturing process and what controls need to be in place.

Seal and filter

Which is the best seal for filtration applications?

In new product design processes the integration of the sealing element(s) are frequently overlooked or considered an afterthought.   Our technical team at Darcoid is driven to help you develop the best possible seal for your unique application.  Frequently, filter seals need to function in mass produced low tolerance injection molded, cast or stamped metal housings and grooves.  These can present challenges in seal design.  Darcoid knows how to leverage elastomer performance characteristics to bridge these challenges to get you the best seal.

In house testing at Darcoid

Our Test Bench team is experienced in running custom “soup mix” fluid combinations to understand the effect of exposure to multiple chemicals on material volume swell or compression set.  We always recommend engaging with a Darcoid applications engineer  as early in your project as possible to assure your project timeline and budget stay on track.

Risk management: Preventing “Performance Creep”

A critical part of your program’s success is making sure the seal that gets assembled in your factory 4 or 5 years from now performs the same as the seal you qualify for production release.  Small omissions or assumptions in your control specs can create major headaches in the future. Darcoid Applications Engineers will share how to control Seal Performance Creep so you can rest easy and focus on your next great development.
