Chevron® Universally proven multi-lip packing
Description Chevron® (known as Shallex® in some regions) is our universal multi-lip packing set that is highly regarded for its long working life and ability to operate under adverse mechanical conditions. When used in split form it can provide major downtime savings. Rod / gland seals
This robust packing set comprises a gland ring/female adapter, header/male adapter, and one or more intermediate V-shaped rings. The rings are tapered to give an initial interference fit when confined in the seal housing. The resulting radial force together with the fine finish of the lip, ensure a good seal at low or slack pressures. A scarf abutment is used when the seal is needed in split form.

Solosele® G Robust single element seal
Description Solosele® G is our compact rod/gland seal and single-acting piston seal that saves space without compromising its high integrity sealing capabilities.
It comprises a profiled elastomeric sealing element that is firmly protected by an Rod / gland seals integral anti-extrusion element of rubber- proofed fabric. High integrity sealing is enhanced by its flexible chamfered lips.
In operation, the elastomeric element provides low-pressure sealing by means of radial squeeze. As pressure increases, its pressure responsive action maintains the sealing force — even when there is significant rod misalignment. Typical applications Materials of construction Rod seal for hydraulic cylinders; ram seal Elastomeric sealing element The tough integral fabric/rubber base for hydraulic presses; or single-acting Standard material: medium nitrile (NBR). resists extrusion whilst being sufficiently piston seal.

Description Twinset is our pressure responsive packing set that boasts a record of success stretching back over 50 years. Although we recommend our more advanced designs for many of the traditional Twinset applications, this product remains a firm favourite with Rod / gland seals the operators of older hydraulic plant.
The packing set comprises an endless U-ring firmly supported by a header ring. The lips of the U-ring are slightly flared to provide an interference fit for initial sealing. When system pressure is applied, the sealing force is increased significantly by reaction within the tongue-shaped cavity of the U-ring.

Lionsele® G High performance single-acting seal
Description This compact rod/gland seal provides optimum sealing performance combined with smooth operation and low levels of breakout and dynamic friction. These features are efficiently achieved by using a PTFE sleeve supported by a Rod / gland seals rectangular elastomeric energiser.
In operation, the rectangular energiser helps to keep leakage to a minimum by evenly supporting the PTFE sleeve, preventing it from twisting or rocking in the housing. Stable fluid film conditions and consistent low friction values are therefore maintained.

Description Lionsele® U2 is a compact U-profiled rod/gland seal of high-performance polyurethane. Its asymmetrical design ensures sealing integrity when cylinder rod/ram deflections occur.
In operation, the secondary sealing lip Rod / gland seals traps fluid behind the primary sealing lip and serves to increase lubrication. This prevents dry running, thus reducing the risk of stick-slip action. Seal life is significantly increased by the optimised fluid film conditions created beneath the primary sealing lip.
Moreover, the secondary sealing lip helps to exclude contamination from the primary Media capabilities How supplied sealing lip, further promoting seal life.

WARNING: Please note that, due to the complexity of making a material selection for any given duty, all information provided in this document on chemical compatibility is intended only as a guide. For example, a compound compatible at low temperatures may show considerable deterioration at high temperatures; also, combinations of chemicals in a fluid medium may have detrimental effects. Actual service life will depend on type of application, whether static or dynamic, specific pressure medium, temperature cycle, time of exposure, etc. The low temperatures quoted are generally values at atmospheric pressure and may change at elevated pressures. If any doubt exists, please seek advice from James Walker.
