Kuri Tec
Polywire Plus
K7300 Series
Heavy Duty Wire & Yarn Reinforced Food Grade PVC Vacuum/Transfer Hose
GENERAL APPLICATIONS
- Ideal for applications which require the hose to withstand both high vacuum and pressure
- Liquid food transfer
- Pressure and vacuum applications which require excellent kink resistance
- Water transfer
CONSTRUCTION
- Tube – Transparent phthalate free PVC
- Reinforcement – Reinforced with high tensile yarns and helically wound spring steel wire
- Cover – Transparent phthalate free PVC
COMPLIANCE INFORMATION
In compliance with applicable FDA(03) requirements, NSF(11) certified, meets USDA(16), 3A(01) and RoHS(14)
SERVICE TEMPERATURE RANGE
+25°F (-4°C) to +150°F (+65°C)
FEATURES AND ADVANTAGES
- NSF 51 Certified Hose – Hose material certified by NSF for use as a drinking water system component. NSF 51 printed directly on hose for easy inspector field verification.
- NSF 61 Certified Material – Tube material certified by NSF for use as a drinking water system component.
- Steel Wire Reinforcement – Electrogalvanized steel wire reinforcement prevents kinking and collapsing.
- Braided Fabric Reinforcement – High tensile strength, food grade, polyester yarn braid provides higher working pressures.
- Transparent – Allows for visual confirmation of material flow.
- Glass-Smooth Interior – Ensures smooth flow of material and reduces material buildup.
- Static Dissipative – Steel wire can be grounded to help prevent the build-up of static electricity for added safety (see below‡).

NOTES:
† Working Pressure decreases as temperature increases. Pressure ratings can only be obtained with proper coupling procedures.
• Use of compression fittings with Kuri Tec® yarn-reinforced hose is not recommended. Claims involving use of these fittings will be disallowed.
CAUTION: ‡This product is designed to dissipate static electricity when the metal wire is properly connected to ground, through the fitting or other means.
