HALLITE SEALS: OPTISEAL SPRING LOADED SEALS

Seal & Design offers a range of OptiSeal® spring loaded (or spring energized) seals. 

HALLITE OPTISEAL® PROFILES

Profile

Description

The standard OptiSeal® design is your best chance at solving sealing problems associated with chemical attack, and temperature. The standard profile shown, is used in the widest range of applications.

The Flanged OptiSeal® design prevents the seal from spinning in rotary applications. In cryogenic applications, the clamped flange reduces thermal contraction on the OD of the seal.

The OptiFace seal is designed for internal and external axial squeeze applications such as flanges, swivel joints, and sealing vacuum. For static applications, beveled lips are a good choose because they offer the highest unit loading.

Unlike the Flanged OptiSeal®, the OptiOil rotary shaft seal doesn’t require a sophisticated housing design. The seal is kept from spinning by the use of an O-Ring on the static sealing surface.

InfoNote: An optional silicone filled spring cavity, shown, prevents the media from coming into contact with the spring. This is a benefit for applications running in sanitary processes such as food and pharmaceuticals, and when you need to protect the spring from the media.

HALLITE OPTISEAL® PROFILES

Profile

Description

The OptiBack, like any back up device, increases the operating pressure capabilities of the seal. When made from materials such as our Arylex® 745 compound, they assist the primary seal in a number of ways:

  • Higher Pressures up to 30kpsi
  • Higher Temperatures
  • Creates Minimal Clearance Conditions
  • Aids in the Alignment of Hardware

InfoNote: If for some reason there isn’t enough axial gland length to use the OptiBack, this integral back up design offers the same benefits and there are no loose components to confuse.

HALLITE OPTIPACK®:INCREASING THE LIMITS

Profile

Description

The OptiPak® design combines packing benefits with the Optiseal®. This redundant sealing design is the answer to high pressure spikes, large extrusion gaps, potential misalignments, and rough surface finishes. OptiPak applications include stem packing, seat seals, geothermal services, swivel joints, and other severe service applications.

Female Adapters made from our Arylex® 745 compound make the first major contribution to OptiPak® performance:

  • Higher Pressures up to 30kpsi
  • Higher Temperatures
  • Creates Minimal Clearance Conditions
  • Aids in the Alignment of Hardware

PTFE/TEFLON™ (the trademark is owned by The Chemours Company) and rubber Vee Rings give the assembly the benefits of redundant sealing. Most of our standard vee ring profiles get used in OptiPak® designs.

The OptiVee is the tie between OptiSeal® and conventional packing. The design varies depending on the location of the ring within the assembly.

Pak Rings are the defense against back side pressure, and the answer to pressure bypass and bi-directional sealing.

The “S” Lip profile was designed by CDI and is used in more of our designs than any other lip profile. Redundant contact areas divide the load and create the best combination of wear and sealability, suitable for the widest range of applications.

The “A” Lip profile is used when wear and friction are a concern. The large radius lip creates a larger contact area, reducing load. Ideal for dynamic applications with high surface speeds.

The “B” Lip, or beveled lip profile, has the smallest contact point and the highest load. This is the choose when wear and friction are of no concern such as in static applications.

The “J” Lip, or scrapper profile, is designed around our “S” profile, and is used when the seal has to function as a scraper or wiper.

HALLITE SPRING ENERGIZERS

Profile

Description

The Vee Spring is the only spring to consider for dynamic appliations. The design goal is to engineer the correct spring deflection, yielding the recommended load.

The Flant Band Helical springs high load makes it ideal for static applications, basically forming a gasket between the spring energizer and the gland housing.
