Corrosion ResistanceWith a corrosion resistance classification of CRC 1 (low corrosion stress), the Festo QSML-1/8-4 is suitable for environments where exposure to moisture or chemicals is a concern. Its PBT housing and NBR seals provide excellent resistance to corrosion, ensuring a long service life.

Compliance with StandardsThe QSML-1/8-4 conforms to RoHS standards and is designed to operate with compressed air in accordance with ISO 8573-1:2010. This ensures that the fitting meets international quality and safety standards, providing peace of mind for users.

Maritime ClassificationAlthough not explicitly stated in the description, the maritime classification is mentioned as "see certificate," indicating that the fitting has been tested and certified for use in marine environments, adding to its reliability and versatility.

Material DurabilityThe fitting's housing is made from PBT, while the release ring is made from POM. The tube seal and hose clamp component are made from NBR and high-alloy stainless steel, respectively. This combination of materials ensures durability and resistance to wear and tear.

Easy InstallationWith a push-pull principle design, the QSML-1/8-4 is easy to install and remove. The external hexagon connection makes it simple to secure the fitting in place, ensuring a secure connection every time.

Blue Release RingThe blue color of the release ring provides visual identification, making it easier to locate and operate the fitting. This color coding also helps in distinguishing it from other fittings in a system, reducing confusion during maintenance or repair operations.
