Polyeal feature of the present invention allows for thermal expansion of the assembly in the seal gland and prevents, for example, the expansion of the assembly to a point where friction between the seal elements and the relatively displaceable part causes additional thermal expansion, eventually resulting in catastrophic seal failure.

A SumoBrain Solutions Company. Additionally, polsyeal elements 30 have an axial notch 62 therein, extending axially into, but not through the seal elements Find related and similar companies as well as employees polyzeal title and much more. The annular seal elements 30 are comprised of a relatively hard wear resistant material, such as nylon. The glide ring piston seal is also difficult to install in a seal gland and is subject to cutting and chipping upon installation.

MacRotech Polyseal IncAddress: While the preferred embodiment of the instant invention is disclosed in detail, it will be appreciated by one of ordinary skill in the art that the instant invention is susceptible to various modifications without departing from the scope of the following claims.

Ratings, reviews, hours, phone number and directions from ChamberofCommerce. The key portion has tapered axial surfaces thereon that are shaped to engage the tapered surfaces of the axial slot of an inverted seal element, thereby providing a pair of inverted nesting elements. This seal assembly has excellent resistance to drift, but the PTFE sealing element cannot bridge small ports and is subject to damage from contaminants in the fluid system.


Unfortunately, rigid dynamic sealing elements require a great deal of force to install, and are therefore vulnerable to installation damage. The instant invention solves the aforementioned problems by providing a seal assembly for a seal gland or groove having a pair of spaced axial walls and a radial wall in a relatively displaceable machine part.

This feature of the invention allows the support element 50 to expand in volume in the circumferential groove 12 while preventing the seal assembly 20 from over-filling the groove 12thereby causing seal damage or possibly failure.

Additional objects, features, and advantages of the present invention will become apparent from the subsequent detailed description, poylseal in conjunction with the accompanying drawing figures.

They can be contacted via phone at for pricing The PTFE element reduces the tendency of pilyseal seal to wear over time but is expensive and difficult to install because it must be stretched into place. The key portion of the annular seal elements has an axial dimension slightly smaller than the axial dimension of the complementary axial slot in the opposing element. Resilient plastic piston ring.

Each annular seal element 30 has a key portion 36 extending axially therefrom that engages the axial notch 62 of a corresponding inverted annular seal element Shamban Industrial Products, Turcon Referring to drawing FIG. As shown polysexl FIG. The support element 50 biases the nesting seal elements 30 radially toward the relatively stationary machine part 18 thereby forcing the seal elements against the part 18 to effect the sealing thereof.

Additionally the axial dimension of the key portion 36 of each seal element 30 is preferably slightly less than the axial dimension of the axial slot 32 thereby engaged, as best seen in FIG.


In an alternative embodiment of the instant invention as shown in FIGS.

A yet further object of the invention is to provide a seal assembly having a support element that ensures that the assembly retains proper orientation in the seal groove throughout the useful life thereof. Additionally, the less flexible dynamic sealing elements require strict attention to manufacturing tolerances to obtain an accurate fit in the piston gland, thereby increasing unit cost.
