Nonconductive smooth bore hoses have straight inner surfaces for applications requiring chemical and high temperature resistance. They have inner tubing that does not allow static electricity to flow through them.

Convoluted hoses have spiral convolutions around the exterior of the PTFE tube that increase flexibility. Their inner tubing does not allow static electricity to flow through them.

Nonconductive smooth bore hoses have outer covers of Santoprene, which protect their stainless steel braided layer and increase resistance to chemicals, oils, and heat. These hoses have straight inner surfaces and inner tubing that does not allow static electricity to flow through them.

Conductive smooth bore hoses have inner tubing that dissipates electrostatic charges for applications where there is risk of electrical charge build-up. These hoses have straight inner surfaces and are suitable for use with fuels, lubricants, and flammables.
