V Ring Packing Seals
This hydraulic packing was subsequently expanded from its original use in steam engines to.
V ring packing seals. Packing seal lubricating rings. Mfp offers a wide range of stack able packing designs. The v ring is an all rubber seal available from all seals it is mounted directly on the shaft by hand and seals against a counterface. These leather v ring packing seals handle over twice the pressure as ptfe.
Begin with a male and female adapter then add v rings between them to fill the space. Vee packing sets are composed of a top and bottom component with a varying number of center vees. Stack as many v rings as you need to fill grooves in valves pumps and cylinders each additional ring adds to the sealing force. Commonly called vee packing or w packing the sets are made of top and bottom adapters with pressure rings in the middle.
No special demands are placed on the surface finish of the shaft seating and the v rings act as flingers since they have an interference fit on the shaft and rotate with it. Leather is tough pliable and wear resistant so it flexes to fit uneven surfaces and fill voids. Stack as many v rings as you need to fill grooves in valves pumps and cylinders. Vee packing is a highly adaptable sealing product.
V ring seals are mounted on shafts and their thin tapered lip seals against a surface counterface at right angles to the shaft. Install between layers of packing seals to ensure lubricants are distributed evenly. Choose from a wide range of stack able packing designs like metric vee packing or v ring packing. It is typically used in adjustable gland applications such as telescoping truck hoists pumps and valves.
In 1928 garlock palmyra developed its chevron packing the first automatic hydraulic packing using standard duck and rubber tubing which it continues to manufacture. Ptfe has excellent chemical resistance and withstands a wide temperature range of 110 f to 500 f. Get more information on v packing seal sizes from catalog. Made of ptfe these v ring packing seals have excellent chemical resistance and withstand a wide temperature range of 110 f to 500 f.
Packing seal lubricating rings. The male and female adaptors are used to complete a set of vee s and to assist in sealing when compressed. Each v ring adds to the sealing force. Vee packing v packing are multiple lip chevron packing sets designed to seal static reciprocating and centrifugal applications.
Designed with a long flexible lip the v ring can act as a face seal a lip seal or slinger. Each set consisting of a number of rings and the pressure rating of these sets is driven by the total configuration.
