Hydraulic Seals
Daemar’s line up of hydraulic seal products has been developed to provide exceptional value by combining the quality and performance that design engineers require with the total cost of ownership savings that today’s businesses demand.
Technical Resources
Loaded Lip Seals
Loaded Lip Seals are very versatile and can be used as rod seals or piston seals. They are considered to be multi-purpose seals and are designed for significantly improved performance.
U-Cups
U-Cups derive their name from their shape and are self-sealing on both the inside diameter and outside diameter. They are most often used for sealing rams or rods and are very popular due to the small gland space required.
Rod Wipers
The main function of the Rod Wiper is to keep the rod and cylinder clean and free from foreign matter; thus preventing premature failure.
Metric Wipers
Metric Wipers are the same as Rod wipers just are available in metric sizes.Some styles are are capable in surviving hostile environments.
Wear Rings
DMR Wear Rings are Glass Filled Nylon. The use of these non-metallic wear rings totally eliminates metal-to-metal contact and the subsequent galling and scoring of cylinder bores and rods.
Wear Strips
Wear strips are designed to eliminate scoring in hydraulic and pneumatic applications by preventing metal to metal contact. They are used in reciprocating, rotary, and oscillating motion environments.
Piston Seals
Two-part seal requiring no lubrication. Provides bi-directional sealing.Easy installation and removal, and can be cut in the field for easier installation.
T Seals
The T-Seal is compact and provides an excellent option to bulkier types of seals in a double or single acting application. The T-Seal is used in reciprocating hydraulic and pneumatic equipment and in high-pressure applications.
Vee Packing
DMR Vee Packings are multiple-lip (chevron) seals comprised of a group of endless rings and are popular for sealing rods and pistons.
Piston Cups
Piston Cups are primarily used on piston heads, plungers or rams in hydraulic or pneumatic service. Piston Cups are commonly used because of economical cost, excellent service life, efficient assemble, universal acceptance, and simple accessories.
Metric Compact Piston Seals
Work the same as regular piston seals just in metric. Lubricants such as oil and grease are able to penetrate the fabric and allow the seal to be highly wear resistant.
Back Up Rings
Back-up rings are washer-like devices that are used to prevent a seal from extruding through any gaps while under pressure. Back-up rings are not seals themselves, but are usually used in conjunction with O-rings in high-pressure applications. Typical applications include hydraulic cylinders and high-pressure hydraulic systems, and high-pressure valves.
Buffer Rings
Buffer Rings buffer the pressure spikes of hydraulic systems. They act as a primary rod seal, and at the same time enable trapped fluid sealed by the secondary seal, which is down stream of the buffer, to be pumped back into the system. Buffer seals are commonly used for rod seal application only.
