How often do I have to change the seals?

Seal life is difficult to predict due to the wide variety of applications using FasTest products. Typically you can be assured of several thousand cycles, however sealing rough surfaces, threads or features may reduce seal life. Other factors such as seal materials, test media, cleanliness, actuation pressure and operational procedures effect seal life.   For additional assistance or to discuss specific applications, contact the FasTest technical product group through the Technical Support page or email your request to


How do I find replacement seals?

Replacing worn or damaged seals at the appropriate time is the best way to ensure your FasTest connector is working as intended.  Finding replacement seals for your connector is now possible through the FasTest website.  Seals can be found with just a few clicks. Additionally, Operational and Maintenance Instructions are available for all products.


Can fluids be used for testing?

This would be dependent upon the fluid media used.  FasTest primarily utilizes Nitrile, Neoprene and Urethane seal materials.  Other materials such as Silicone, EPDM, Viton, etc are available for fluids that may have compatibility issues.  Some fluids can wash away the internal lubricants of the product, so periodic preventative maintenance is always recommended. Steam, O2 and volatile solutions are not recommended unless specifically referenced in our product information for these fluids. For additional assistance or to discuss specific applications, contact the FasTest technical product group.


Can connectors be used underwater? 

FasTest products are manufactured primarily from corrosion resistant stainless steel and/or anodized aluminum.  These connectors will function well in underwater tests. The exceptions would be the ST & XT Series refrigeration products, manufactured from carbon steels.


Can we customize threads, seals, etc?

Yes!  FasTest has a highly knowledgeable technical product staff to assistance with special and custom applications.
