Hydraulic Seals

At Bergman Specialty Products we endeavor to stock the very best products to meet all of your potential needs. We have certainly accomplished our goals with our hydraulic seal department. Utilizing great brands like Hallite, Parker, Poly Seal, Trelleborg and Markel, our products are available in many materials such as Buna, neo/fab, Viton, Urethane, Teflon and many more, each tailored to a specific need or situation. We have both metric and standard sizes to offer to be sure that our seals fit outdated or refurbished equipment without issue. Not only that, but we offer great pricing options as well, complementing them with fantastic customer service. So just what do we have in stock?

To begin, we have many types of hydraulic and pneumatic seals, including pistol seals, devices connected to the pistol rod to assist with its mobility. Short and cylindrical in appearance, they are available in materials like leather, NBR, Polyurethane, neo/fab, Viton and Teflon. Also available are rod and t-seals, both usable in most standard o-ring grooves and including built-in backups to resist extrusion and twisting. The devices help seal against high pressures and temperatures, but work just as well when these factors are low. They are able to fit into existing grooves without the hassle of re-machining or even design revisions. We offer the rod seal in both metric and non-standard sizes and well as standard options based upon the parameters of your desired application. Bergman is also pleased to carry a wide variety of packing rings, beginning with the O-ring, used to prevent pressurized leaking and including quad-rings, which provide a bit less friction than O-rings, and square rings used for higher pressure situations.

Bergman Specialty Products also offers wipers of a diverse range of sizes, including metric and standard options, as well as a variety of materials. Highly useful in both hydraulic and pneumatic applications, the device is used to wipe the cylinder and serves as extra protection to keep out fluid contaminants. Also available are a great deal of wear bands and wear rings. Used to guide the piston through the cylinder while keeping it aligned, wear bands and rings eliminate the possibility of metal to metal contact which might damage the cylinder wall and/or piston, causing premature wear on sealing components. Usage of wear bands/rings can greatly extend your system's sealing life, allowing you to use less water and prevent other problems. Wear bands and rings come in many materials like nickel, bronze and stainless steel-filled Teflon, as well as Phenolics and nylon.

V-SETS
Sets, otherwise known as vee packings, are commonly used tools for sealing rods and pistons.

V-Sets, otherwise known as vee packings, are commonly used tools for sealing rods and pistons. Useable in both low and high pressure applications with both single or double-acting cylinders, v-sets are composed of a top ring (aka a female adaptor), a bottom ring (the male adaptor) and center rings called chevrons. Chevrons are used as the primary pressure/sealing element in the set, while the top and bottom rings serve to guide your centers and make them sturdy. Vee packing is still used today in newly manufactured cylinders and is a very good choice for worn cylinder bores and rods. There's a reason they're so popular, and so commonly used. V-sets are a terrific tool for making sure your project is able to reach its full potential. The composition of a v-set is very significant. As such, Bergman Specialty Products is proud to offer you a wide range materials which can be used for different pressures and applications. For example, neoprene or homogeneous v-rings are primarily designed for pneumatic service or lower pressure air, while Nitrile and fabric rings are specified for higher pressure applications. We also offer materials such as Buna, Epdm, Viton and bronze, carbon and glass-filled Teflon. Don't worry about those prototype builds, or getting the right seal with the right pre-load, as we only need your metal dimensions to build the proper seal for you. Call us today so that we can begin building the exact product you need. Here at Bergman Specialty Products, your satisfaction is our top priority.

POLY SEALS
The Poly Seal is a squeeze-type seal which provides an even load of pressure on the seal lips, allowing for an effective seal at very low pressures.

The Poly Seal is a squeeze-type seal which provides an even load of pressure on the seal lips, allowing for an effective seal at very low pressures. As pressure increased, the lip loading is automatically increased to compensate so that the seal can continue to maintain a strong, leak-free fit. At lower pressures, they are more effective than conventional U-Cups, which are more prone to leaking under such conditions. There are a few types available, all of which we carry. Standard Poly Seals are square and are suitable for a wide variety of rod and piston applications. Deep Poly Seals on the other hand are rectangular. Their added height improves stability for heavy duty applications wherein they will have to endure high levels of shock. Finally, Type B Poly Seals add a back bevel lip to the Deep Poly Seal design, aligning the seal interface near the centerline of the o-ring to provide increased squeeze, which in turn raises the level of stability. Regardless of the type you choose, all of our poly seals provide excellent low pressure and super high pressure functionality. However, don't just take our word for it. Here at Bergman Specialty Products we offer a huge range and variety of poly seals. Whether you require the Standard, Deep or Type B model, chances are high we have exactly the poly seal you're looking for. However, the only way to know for sure is to call and find out. Why not do so today? You'll speak to one of our highly acclaimed customer service representatives who will put you in touch with an expert to help you select exactly the right product for your project whatever its specifications. From low to extremely high pressure, Bergman's poly seals will have you covered.

QUAD RINGS
Rings, sometimes known as X-rings, are a very versatile alternative to the standard o-ring.

Rings, sometimes known as X-rings, are a very versatile alternative to the standard o-ring. Useful in a myriad number of applications, both static and dynamic, quad rings offer additional stability through virtue of their design. The ring's four-pronged design helps to circumvent the problem of spiral twisting. By providing double the sealing surface of an o-ring, quad rings allow for a reduction in friction (by requiring less squeeze) and, by extension, a potentially longer life for your seals. Due to their construction, they are less prone to leaking than o-rings as well. Not only that, but quad rings can be used in standard o-ring grooves, as well as those more narrow than is typical. In this way, quad rings allow for easy installation, with no revisions or redesigns necessary for their installation. We are proud to offer quad rings in a wide variety of materials including Polyurethane, Butyl, Aflas, Neoprene, Silicone, EPDM, Viton, Kalrez and Viton. Our products are also available in both metric and standard sizes. Basically, whatever your quad/x-ring needs, there's a very good chance that Bergman Specialty Products has just what you're looking for. Call us today and inform us of the nature of your project and your precise needs. We'll find just the right part for you.

SQUARE RINGS
As well as offering standard o-rings, Bergman Specialty Products carries a variation called square-rings.

As well as offering standard o-rings, Bergman Specialty Products carries a variation called square-rings. Apart from differing in their shape, the two seals have a variety of differences between them. Frequently even cheaper to produce than their circular brethren the physical sealing ability of square rings are a bit higher, but only in static applications. In the field of dynamic applications, o-rings are more reliable. In fact, if you're thinking of installing square rings into a dynamic application you should know that they have a very limited number of roles they can fill in that particular realm. That being said, if you're looking for a seal for a static application, square rings are a great bet. We are pleased to offer square rings created from a great range of materials including Polyurethane, Butyl, Aflas, Neoprene, Silicone, EPDM, Viton, Kalrez and Viton. Our products are available in both metric and standard sizes.
