Boss Process offers Static Seal 2- and 3-bolt stainless steel couplings, developed specifically for the plastics industry and dilute-phase applications with relatively low static pressures. Constructed with a T430 stainless steel body and available with SBR abrasion-resistant gaskets or FDA-compliant NBR gaskets, these stainless steel compression couplings are rated for up to 60 PSI static pressure.
Static Seal couplings are designed for plastics processing applications. The T430 stainless steel outer body, combined with Grade 5 zinc-plated bolts, provides durability for industrial vacuum and pneumatic conveying systems. They are available in sizes ranging from 1.50" OD to 4.00" OD.
Advanced Eyelet Design for Superior Static ConductivityThe proprietary eyelet design distinguishes these anti-static compression couplings from conventional alternatives. This advanced feature helps dissipate static charges while minimizing gasket movement caused by system vibrations. The eyelet design provides superior static conductivity throughout the coupling's service life.
Gasket Options and Bolt ConfigurationsChoose between abrasion-resistant SBR black gaskets or FDA-compliant NBR white gaskets. For high-temperature applications, white VMQ silicone gaskets are available by special order. These stainless steel couplings are offered in 2- and 3-bolt configurations. Stainless steel gasket protectors are also available as an optional feature.
