V-packing are used in hydraulic system components at various locations. They are made of fluorocarbon reinforced with cotton, asbestos or neoprene reinforced with asbestos for high temperature & exotic fluid application. V-packing are available in split to facilitate assembly and specific sizes. V-packing is popular for both single and double acting duties on servo-motors. V-packing is a stacked sealing system. A V-packing set generally consists of a female adapter, 2 to 5 V-rings and a male adapter. The V packing is backed by an annular packing-ring sliding in the bore of the cylinder-head.

Valve Seals are used to minimize process fluid leakage along the stem that connects the internal parts with the external actuator. These seals leak to minimize product release and maintain valve seals in good condition. The valve seals are usually made of neoprene. Valve seals are used to limit the amount of oil that is used to lubricate the valve stem and valve guide. Valve seals keep oil from draining down through the space between the valve stem and the valve guide. Valve seals for the intake and exhaust valves are commonly of different designs & materials. These valve seals are replaced without removing the cylinder head. There are three basic designs of valve seals such as positive lock, umbrella type and simple o-ring seals.

Viton tubing is electrical grade modified fluoroelastomer tubing rated for -55°C to 200°C continuous operation. It is very abrasion resistant, flexible and resistant to most fuels, acids and alkalis. It is typically used as a wiring and component cover in aircraft and aerospace applications and chemical plants.

Whiting powder is a non-abrasive powdered cleaning agent that cleans excess flux, oil, cement and other residue from stained glass projects. It is used as a cleaning agent to help remove all forms of residue. Sprinkle dry over entire glass panel surface and rub with a soft cloth or stiff soft bristled brush.

Wipers operate electrically and speedometer includes trip indicator. The wipers are subjected to high temperature when the separator is used as the receiving unit in the drying system. The wipers are inspected periodically for wear and damage. Each wiper has slotted fastening holes and adjusted to the screen as wear occurs. The wipers are made for all planes with speeds up to 300 MPH. Wipers serve to bridge together the individual contacts and the circular strips.
