Cup Packing Seals
Cup Packing Seals


The cup seal packings are designed to seal reciprocation pistons, plungers or rams. The cup seal packing provided by us can be impregnated in a variety of ways including thiokol, carnauba wax and more. These cup seal packings are available in different sizes and we also customize them as per the specification of the customers.

Chevron is a universal multi-lip packing that is highly regarded for its reliability, long life and ability to cater for adverse mechanical conditions. It is suitable for use in split form. The chevron seal sets are arranged in 3 different versions. Type a: has 3 to 5 fabric seals, and can be installed in adjustable or non-adjustable sealing areas. Type b: has 3 to 5 fabric seals, one rubber-sprung support ring and are installed in non-adjustable sealing areas. It has constant axial pre-tension. Type c: has 2 to 4 fabric seals, one rubber packing and can be installed in adjustable and non- adjustable sealing areas. For increased sealing effect- type a and b can be supplied in open form. Type c is always supplied closed. Examples of use: injection molding machines, iron and steel industry, compression moulding, special cylinders, marine hydraulics, steel hydraulics engineering and scrop metal shearing. A cup seal packing can be used for a hydraulic piston-cylinder device the cup having an outer lip with a leading edge adapted to slide along a wall when fitted in the device. The angle a of the leading edge with respect to the cylinder axis is made smaller than the angle of a portion other than the leading edge with respect thereto, and is made as 1°=a=15° in the free condition of the cup. When the sealing cup is installed to be slid in the cylinder, a wedge-shaped clearance is formed between the leading edge and the cylinder wall due to provision of the angle a, thereby admitting the fluid therein to decrease the slide resistance of the sealing cup.

In vehicles, lots of devices have been employed for pressurizing the fluid in which a piston fitted within the cylinder and a cup mounted on the piston constitute a cylinder chamber to be pressurized by the relative movement of the piston and the cylinder. In the field of brake devices, too, various improvements have been made to sealing or piston cups (hereinafter simply referred to as brake cup) in order to increase the sealing effect from the view point of safety. As a result, the seal requirement of the brake cup has been satisfied. Recently, a new requirement of vehicle drivers is to improve foot feeling upon depression of the brake pedal. That is to say, the brake device has to provide a brake pedal that may be smoothly depressed with little resistance and which will stop the vehicle with a small depression of the brake pedal.
