TF 1572 SAN NSF-61 CertifiedRestructured PTFE and Glass Spheres
Description and Applications
Drinking Water Service:
TEALON TF 1572 SAN is suitable for service with a wide variety of aggressive media, but is specifically formulated to allow compliance for drinking water system components with NSF-61, from source to tap. Certification to NSF-61 provides assurance to a highest level that TF 1572 SAN is safe for use in drinking water service. The high compressibility of this style makes it particularly suitable for use with stress sensitive and/or fragile flanged joints, e.g. glass, ceramics, plastic, etc.
Isolation:
An added benefit is that TF 1572 SAN has a strong dielectric rating, making it suitable for isolation kit applications.
Construction:
TEALON TF 1572 SAN is a structured PTFE - Gasket - Sheet manufactured by a unique process which provides a high level of fibrillation to overcome the creep relaxation and cold flow problems associated with normal (skived or molded) PTFE sheets. This style is produced from virgin PTFE resin filled with hollow glass microspheres.
