Industrial-Strength Hydraulic Seals for Diverse Industries
Wood Industry
The hydraulic products we manufacture are for the plywood, oriented strand board (OSB), particleboard, medium-density fibreboard (MDF), pulp, laminating, and melamine businesses. They generally manufacture their products on multi-opening presses operated by hydraulic oil.
The most common hydraulic presses found in these industries are manufactured by the following companies: Washington Iron, Dieffenbacher, Fjellman, Motala, Williams, White & Company, Siempelkamp, Globe, and Superior. Specialty Sealing Technologies has been supplying the products for the main rams, jack rams, loaders, and unloaders.

Extrusion and Forging Industry
These industries require the most durable and robust design packings in the market today. We offer a heavy-duty style packing that is widely used in these industries. The sealing rings are designed and manufactured to accommodate higher pressures, heavier workloads, and deeper stuffing boxes. The packing will work in standard hydraulic fluids, water, or an oil-water mix.
Extrusion Applications
Forging Applications
Compression Moldings
Robust V-Pack and Robust Floating V-Pack
This packing is manufactured primarily for heavy and harsh sealing applications. The sets are constructed from molded fabric and rubber consisting of a series of intermediate (V-rings), header (male) and gland ring (female). All the rings are taller in height than the standard V-pack, which offers greater strength for harsh conditions. The header ring is normally supplied from molded fabric to offer greater compression and strength to the set.
Robust V-Pack
This packing is manufactured for applications when a heavier and taller set of rings are needed. All rings are molded with the purpose of use in heavy applications where they will encounter high pressure and abnormal side loads. The set is to be used when filling deep stuffing boxes.
Robust Floating V-Pack
This packing is manufactured for applications when a heavier and taller set of rings are needed. All rings are molded with the purpose of use in heavy applications wherein they will encounter high pressure and abnormal side loads. The sets are to be used when filling deep stuffing boxes. Floating V-pack is manufactured to float inside the seal housing. All rings are taller in construction and normally a larger cross section.
The floating V-pack is intended to be maintenance-free once installed. The packing is not compressed with a built-in interface, which allows the (male) manufactured will seal under low pressure up to 8000 PSI.
Hydraulic Cylinder Repair
We provide seals with nonstandard cross sections in small quantities, without mold or set-up charges. Simply let us know the specifications, and we’ll fabricate the hydraulic seals depending on your industrial application.
