Hi-Tech Seals, Inc. Datasheets for Dynamic Seals

Dynamic seals include oil seals, hydraulic and pneumatic seals, exclusion seals, labyrinth seals, bearing isolators, and piston rings. They create a barrier between moving and stationary surfaces in applications such as rotating shafts and pistons rings.  This is a general search form; more detailed search forms are available.

Product Name Notes
A fabric reinforced 70 durometer nitrile seal, that is compressed axially and seals where the casing hanger and tubing meets. A steel plate holds the compression seal in place and...
Back-up rings are plastic or rubber rings used to prevent the O-ring from entering the clearance gap. When high pressures are exerted on the O-ring its soft rubber material can...
Change the description to: "Our Blue/Black Vee packing sets are constructed of Hytrel® (blue) and Nylon (black) Vee's. The material properties make it excellent for operation in fire resistant fluids.
Hi-Tech Seals can supply both piston and rod buffer seals, however, the majority of our stock consists of rod seals. Buffer seals are usually used in combination with a U-cup...
Hi-Tech Seals sells the sealing components of a blowout preventer. With the help of the blowout preventer the well can be safely sealed off when needed. Safety is a priority...
Hi-Tech Seals stocks Secondary Wellhead Seals that are 70 Duro NBR. Available in 5 different sizes. These Seals are located in the Secondary Packoff of a Wellhead Assembly.
Homogenous U-cup (block vees) are non-loaded, single material U-cup. The Homo U-cup (HU) is popular in low pressure applications where a low friction seal would be beneficial. The seal is...
Modular bearings are used in both rod and piston applications. Modular bearings act as a wear and load bearing surface to help extend the life of a U-cup. The standard...
Piston cups are molded packing that have a single sidewall, complete with a sealing lip. The sealing is done by the outer lip, which is beveled and holds pressure unidirectionally.
Piston rings are excellent for sealing for sealing in hydraulic and pneumatic cylinder applications. The piston rings provide excellent low friction with strong chemical resistance. By changing the material of...
Single acting fluid seals (SAFS) are commonly used in stage cylinders for truck box hoists. SAFS are often used with anti-extrusion rings either on ID or OD depending on rod...
SpectraSeals® are engineered plastic seals incorporating a metallic spring, which loads the seal lips against the mating hardware, creating a seal. The spring also allows the seal to follow minor...
The function of a V-seal is to exclude dirt, water, or other aggressive media from entering bearing housings while also retaining grease. The V-seal stretches over the shaft and assumes...
The oil seal was originally developed to seal on automobile bearings but it is now used in a wide range of applications. The oil seal will create a tight seal...
The primary function of anti-extrusion rings is to take up space in a groove, and/or prevent extrusion of material at high pressures. Anti-extrusion rings can also be used to assist...
The T-seal comes in both piston (TPO) and rod (TRO) styles, and can be installed in standard O-ring grooves. The T-seal is a double acting seal. The Back-up rings and...
The urethane U-cup design provides an excellent heavy-duty seal for either piston or rod applications. Urethane U-cups work well in both static and dynamic applications. The non-symmetric styles (MPI and...
The urethane U-cup design provides an excellent heavy-duty seal for either piston or rod applications. Urethane U-cups work well in both static and dynamic applications. Symmetrical, rod and piston styles...
The V-seal mounts directly onto the shaft and seals axially against a counterface, housing or bearing surface. The elastic body allows for the seal to be stretched into place without...
The Z-Seal is a composite type lip seal. Double lip design provides extended seal life and greater resistance to compression.
U-cups are lip seals and are primarily intended for dynamic applications. Fluid or air pressure forces the sealing lips into contact with the surface to be sealed against. Polyseals are...
Vee packing is a V-shaped seal commonly used in adjustable gland applications. Vee packing is usually used as a stacked set composed of center components, a male adapter and a...
Vee packing is typically used in adjustable gland applications such as telescoping truck hoist, pumps and valves. Vee packing sets are composed of a top and bottom component with a...
Wipers are primarily designed to stop contaminants from entering a cylinder on the rod, however, they can also act as a secondary seal. If contaminants were allowed to enter the...
