Materials and Sizes
Siftex carries rubber tubing in six different rubber compounds.
Compound |
Description |
|---|---|
| Gum Rubber | Best Seller for dry materials processing. Excellent abrasion and tear resistance. Temperatures to 180° F (82°C). |
| Neoprene Rubber | All purpose oil, grease and abrasion resistant. Temperatures to 212°F (100°C). Available in black static-conductive. |
| Carboxylated Nitrile Rubber |
The GREEN alternative to Neoprene. Safer for the environment; doesn’t release chlorine gas during decomposition. Excellent abrasion and oil resistance. Temperatures to 280°F (138°C). |
| Nitrile Rubber | Best resistance to oil and grease as well as excellent abrasion resistance. 3-A Sanitary available. Temperatures to 280°F (138°C). |
| EPDM Rubber | Handles acids, oxygenated solvents and wet or dry abrasive materials. Suitable for outdoor exposure. Temperatures to 290°F (140°C). |
| Silicone Rubber | Best for wet (wash-down) environments; dilutes acids. Suitable for extreme temperatures from -60°F to 500°F (-51°C to 260°C). |

Static-Conductive Channel Tubing
Control static charges without the risk of wires contaminating your product. FDA-acceptable inside and outside product contact surfaces. Make cut-to-length static-conductive sleeves quickly and easily. No static, no static worries!
Unique static-conductive layer is an integral component of the tubing wall circumference. Static conductive layer offers surface resistance of <.01 megOhms.
Simply push a metal clip into each end and connect to metal spouting. Static-conductive channel is located under the branding strip on the outside of the tubing.
Materials and Sizes
Available in two designs: 25 psi pressure rated hose, and lighter weight non-pressure rated flexible tubing.
Both feature a 1/8″ (3.2mm) thick, white FDA-acceptable rubber tube and grey neoprene cover.
Choose from the following tubing compounds to meet your application requirements:
- White FDA Natural Gum Rubber
- White FDA Neoprene
- White FDA EPDM
- White FDA Carboxylated Nitrile
If you looking for a non-FDA option Black Static-conductive Neoprene Tubing is for you. N55C is a high grade Neoprene rubber compound formulated to provide the properties of Neoprene – moderate oil resistance in addition to resistance to the elements. The incorporation of special black fillers provides a high level of electrical conductivity in the finished products as well as abrasion resistance. The compound is rated “conductive”.
