GORE Universal Pipe Gasket (Style 800)

Gore Universal Pipe GasketGORE® Universal Pipe Gasket (Style 800) provides a reliable seal for steel, glass-lined steel and fiber reinforced plastic (FRP) flanges, in the full spectrum of strong acid, alkali, and solvent process media, including the most challenging thermal cycling and elevated temperature applications.

This single gasket solution can reduce the process safety and production downtime risks caused by the use of an incorrect gasket material. Highly conformable 100% ePTFE reliably seals irregular surfaces.

What Makes the GORE Universal Pipe Gasket Unique?

  • Proprietary, patented technology.  GORE Universal Pipe Gasket (Style 800) uniquely combines two patented construction elements, each made of 100% expanded PTFE (ePTFE).
  • A non-permeable barrier layer covers the inside diameter and gasket flange faces, creating a tight seal at low gasket stress.
  • A conformable-yet-strong interior provides superior resistance to creep and cold flow.

Long-Term Reliable Sealing

Unlike conventional (filled and skived) PTFE, expanded PTFE (ePTFE) gaskets are highly conformable to common flange imperfections, creating a tight seal in challenging conditions.

With superior resistance to creep and cold flow, GORE Universal Pipe Gasket (Style 800) retains its dimensional stability through thermal and pressure cycles. Bolt load is maintained, to achieve a long-term reliable seal.

One Gasket, Many Applications

The patented technologies of GORE Universal Pipe Gasket (Style 800) deliver a low stress-to-seal capability that is ideally suited for glass-lined steel and FRP piping systems, while maintaining the material strength required for outstanding performance in steel systems.

Chemically-inert GORE Universal Pipe Gasket (Style 800) provides a highly effective seal for strong alkali-, acid- and solvent-based chemical process systems. Made of 100% ePTFE, it is resistant to all media (pH 0-14) except molten/dissolved alkali metals and elemental fluorine.

GORE Universal Pipe Gasket (Style 800) creates a tight, reliable seal for multiple flange materials, so it can replace multiple other gasketing materials. By streamlining gasket ordering and inventories and standardizing the gasket selection and installation process, using GORE Universal Pipe Gasket (Style 800) across multiple pipe flange materials and process media reduces the process safety and production downtime risks from the use of an incorrect gasket material.

What is a Spring Energized PTFE Seal?


Spring energized PTFE seals perform reliably in a variety of applications where conventional elastomeric seals fail due to chemical attack, extreme heat or cold, friction, extrusion or compression set.

PTFE seals have three basic design elements:

  • A pressure-actuated U-shaped jacket
  • A metal spring loading device
  • High performance polymeric seal materials

So what is a spring energized PTFE seal? It’s a spring-energized U-cup that uses a variety of jacket profiles, spring types and materials in rod and piston, face and rotary seal configurations. They are used when elastomeric seals fail to meet temperature range, chemical resistance or friction requirements.

Jacket profiles are made from PTFE and other high performance polymers. Spring types are available in corrosion-resistant alloys, including stainless steel, Elgiloy and Hastelloy.

Kalrez® 7745 Replaces 1045

Kalrez KLX-16001DuPont™ Kalrez® 1045 parts were phased out of the Kalrez product line at the end of March 2016. Kalrez 1045 parts have a long history of use in dinitrogen tetroxide (nitrogen tetroxide) service.

This chemical is often used as the oxidizer in rocket propellant, when combined with a hydrazine based rocket fuel. Nitrogen tetroxide is a very strong oxidizer, and Kalrez 1045 is resistant to oxidizing liquids; it has been the product of choice for hypergolic propellant applications.

How Parker Sure Torque Gaskets Help Railroads

Rail Yard New regulations are making it tougher to haul goods by railroad. Haulers are spending $2.9 billion to upgrade tank cars, and the use of railroads to transport crude oil declined by 17 percent last year. And starting this year, shippers and terminals will be held responsible for NARs, or non-accident releases.

Our partners at Parker – a long-time Gallagher O-ring supplier – discuss this trend in a recent blog post.

As of last year, NARs has gone up by nearly 20 percent. In most cases, these incidents involved problems with the manway. The four main issues were loose bolts, missing gaskets, misaligned gaskets and deteriorated gaskets.

Parker O-Ring Handbook Goes Digital

Parker O-ring handbook, o-ring ehandbookFor more than 50 years, the Parker O-Ring Handbook has been an engineering staple of the sealing industry.

Now, it’s gone digital.

In 2015, Parker Hannifin Corporation launched an interactive digital reference guide to enhance and broaden the customer reach of the existing Parker O-Ring Handbook, the Parker O-Ring eHandbook.

“I’m constantly amazed and honored at how often I run across it in unexpected places,” says Dan Ewing, senior chemical engineer and materials manager at Parker’s O-Ring division, “I’ve come to expect to see a well-used copy sitting on a customer’s desk, but I’m pleasantly surprised when I find it cited in academic papers, referenced in reports written by government agencies and discussed in industry association meetings.”
