Nitrile. Nitrile is commonly used for fluid power cylinders, but has a range of other industrial applications. It has a rubbery consistency, making it ideal for hydraulic seals, and it holds a number of advantages. Nitrile is particularly cost-effective and also offers remarkable resistance.
What material are hydraulic seals made of?
Materials. Hydraulic seals can be made from a variety of materials such as polyurethane, rubber or PTFE. The type of material is determined by the specific operating conditions or limits due to fluid type, pressure, fluid chemical compatibility or temperature.
Which seal is suitable for the pressure system?
Polyurethane-based materials — such as Molythane (impregnated with molybdenum disulfide to provide dry lubrication plus good compatibility with lubricating properties of working fluids) - are suitable for application pressures up to 5,000 psi without backups.
Which material is used for sealing?
Materials Used to Fabricate Seals A wide variety of materials is used to fabricate seals. Specific to industrial use, materials like industrial rubber, Polytetrafluoroethylene (PTFE), Fluorosilicone (FVMQ), Polyurethane (AU, EU) and others are used in the seal fabrication process.Dec 17, 2014

How do I choose a piston seal?
A few of the important parameters that one needs to consider while selecting a seal are system operating pressure, seal material compatibility with fluid and fluid operating temperature, resistance against extrusion, expected service life, ease of installation, cost of procurement and logistics.Mar 16, 2017
What do the numbers on a hydraulic cylinder mean?
Bore x Stroke (x Piston rod) Typically hydraulic cylinders are broadly categorized in Bore x Stroke. For example, a 4"x24" cylinder has a 4" bore and a 24" stroke. If there is a third number, it's the diameter of the piston rod.Nov 14, 2012
What identifies a double acting hydraulic cylinder?
A double acting cylinder uses hydraulic power to both extend and retract. You can tell if a cylinder is double acting by looking at the number of ports.
How do I know if my hydraulic cylinder is single or double acting?
Single Acting cylinder only extends by pressure from a pump and then retracts by the weight of the load or by an inbuilt spring. A Double Acting cylinder uses hydraulic power to both extend and retract. A simple way to tell the cylinders apart is by looking at the number of ports.Dec 18, 2017
Are hydraulic cylinders interchangeable?
The National Fluid Power Association (NFPA) has standardised the dimensions of hydraulic tie rod cylinders. This enables cylinders from different manufacturers to interchange within the same mountings.Sep 22, 2021
