NIPPON PILLAR’s products include fittings, and other devices for circulation systems, as well as the low wear, chemical and weather resistant Pillar fluororesin products that are designed to meet the needs of a wide range of applications from electronics to construction.
Most notably among their product line is their Super 300 Type Pillar fitting. Enhanced from the original “Super Type” Fitting, the Super300 style fitting uses radial force as opposed to axial force to achieve high-sealing performance. The addition of a “gauge ring” not only secures the union nut more firmly to the fitting body, but also produces an audible “click” once the union nut has reached maximum tightening capacities.
Unique Low-Torque Design
A PFA sleeve inserts into the tube, making a one-piece assembly that effectively eliminates the tube as the primary seal. The sleeve design seals with low torque, which means that hand tight, the S-300 Pillar fitting will stay sealed, even in high temperatures, temperature fluctuations, or high vibration.
Know It’s Tight, Even With Your Eyes Closed
You know it’s properly torqued, every time. The unique “gauge ring” gives an audible “click” that you can feel as you tighten the nut. It also prevents overtightening. You can be 100% sure this Pillar fitting’s tight and made up properly, even if you can’t see it. No need to retighten the S-300 fitting, even in high temperature or high vibration.
The Pillar S-300 fitting was designed to save space. Its low torque and insert design means smaller cross-sections and therefore less space in your tool. The knurled nut allows easy tightening, by and or with the simple Pillar wrench – small, plastic, and easy to fit in small spaces.
