Standard Features
Exclusive 3-Year “No-Leak” Guarantee – VISI-FLO’s innovative radial seal creates a constant and uninterrupted sealing force between the body and outside diameter of the glass lens. This sealing method provides a longer lasting and better seal than conventional flat seals.

Maintenance-Free Design – VISI-FLO’s unique, bolt-on-body design requires no special maintenance or torquing sequence be followed to prevent leaks. This results in a safer, more reliable sight flow indicator than those units using tie rods to fasten lens and seal to body. Dimensionally Interchangeable – “FJP” Flanged VISI-FLO?s feature end-to-end dimensions that match Jacoby-Tarbox and Penberthy and other manufacturers’ units. “FJP” units are available in 3/4", 2", 3", and 4".

Shipment Within 48 Hours on Most Items
Rated for Vacuum Service- up to 635 mm (25”) at 85.5% vacuum. This equates to 12.3 PSI vacuum.

独有的三年“不泄露”担保
VISI-FLO的创新性径向密封设计为壳体和玻璃视镜的外径之间提供了恒定的、不间断的密封力。与传统平面密封（通常带拉杆设计）相比，上述密封方法提供了持续时间更长、密封效果更佳的密封性能。

无需维护
VISI-FLO独有的螺栓紧固壳体设计无需专门的维护或扭转工序。因此与使用拉杆来紧固视镜和密封壳体的产品相比，上述设计更安全、更可靠。
