Micromold's FLUOR-O-FLO® PTFE and PVDF bulkhead fittings allow quick, easy connection of Micromold's PTFE or other piping system to any type of tank: plastic, metal, or lined. The fittings may be installed without adapters in either flat wall tanks, or most cylindrical tanks. To provide the best possible seal, standard fittings are supplied with special FEP encapsulated o-rings which seal to the interior tank wall. The special silicone hollow core o-ring provides sealing flexibility, and also compensates for any creep relaxation which may occur in the fitting body. The FEP encapsulation of the o-ring maintains the superior corrosion resistance of the fitting. For high temperature service, FEP or PFA encapsulated Viton or solid PTFE o-rings can be substituted. Buttress form threads are used on the lock-nut to allow the compressive forces needed to obtain a proper seal of the o-ring against many difficult to seal interior tank surfaces. Available in pipe sizes ranging from 1/8" through 4". PVDF fittings are available NPT threaded, or socket weld for IPS or metric pipe
