The grades and sizes available make PTFE Tubing ideal for applications such as medical, chemical and automotives.

PTFE Tubing is unique in many ways when compared to conventional polymer tubing:

• Highly resistant to corrosive chemicals
• Working temperature range of -200C to +220C
• Chemically inert - making it ideal for medical applications
• Extremely low coefficient of friction
• comes in sizes ranging from 1mm to 25mm diameters.

We are exclusive Distributor for Nomex Filter Bags. Nomex filter bags provide depth filtration and have a high solids retention capacity. All of our Nomex Filter Bags have their outside surface singed or glazed to prevent fabric fibers from the bag getting into the clean, filtered process media.

Nomex felt has the highest melting point of all our filter bags except for PTFE filter bags, making it ideal for hot oil and other applications up to 400 F. Nomex Felt is generally compatible with most fluids except those that are strongly alkaline or strongly acidic.

Nomex Filter Bags are available with both metal and plastic sealing rings. The ring material is important not only for chemical compatibility, but also for disposal purposes. If the bag is going to be disposed of by incineration, it's important that the ring be plastic, and not metal.

We've organized the catalog pages for Nomex Filter Bags by bag size. Follow the link for the bag size you need and the snap-ring material and micron options will be listed along with their prices. All filter bags are sold in box quantities only.

AGM (Absorptive Glass Mat ) is a non-woven fabric made with glass microfiber. It has been available for more than 30-years and has been used in VRLA batteries world-wide.

Characteristics

Admiral Trading Company has a variety of AGM grades uniquely designed for different VRLA applications and manufacturing demands. In general, AGM has the following characteristics :

Absorbency:Because AGM is highly porus ( 90-95%, @20kPa ) that can absorb more acid. Additionally it has small pore sizes to maintain electrolyte levels in the battery.

Durability:Because AGM is highly resistant to battery acid, oxidation and heat, and can maintain its shape and strength after prolonged exposure of sever environmental conditions.

Applications

AGM is the best for the retainer mat for VRLA batteries.

What is a Slideway?
Slideway is a proprietary formulation of PTFE material impregnated with bronze and friction reducing additives.

What does a Slideway do?

• Reduces friction and wear
• Reduces damage caused by mechanical problems
• Increases accuracy
• Extends machine life
• Saves energy

How does a Slideway linear bearing system work?

By providing self-lubricating, low coefficient of friction linear bearing surface between two metal interfaces, is normally attached to the moving surface bya bonding method.

The Slideway bearing moves with the work table or tool holder along the steel or cast iron mating of the tool way. The static and dynamic friction of is nearly the same on both cast and hardened or soft steel ways.

Applications
Planers, milling machines, SPMs, sharpers, horizontal & vertical boring machines, hydraulic & pneumatic power presses, press brakes, all types of grinders, radial drills, automatic screw machines, gear hobbers, gear shapers, multi-spindle automats, broaching machines, CNC machines and machining centres.
the solution you have been looking for to reduce the effects of friction on your machine tool accuracy. It is applicable both for new designs and while rebuilding guideways.
The results conform to the machine tool manufactures' re-builders' specifications.

Advantages
The advantages of Poly Fluoro Slideway tape bearings in comparison with traditional solutions are: Coefficient of Friction: Slideway has the lowest coefficient of friction as compared to other guiding materials.

"Champion" jointing sheet technology is based on a tradition which stretches back over few decades. With close co-operation with our customers, by constant development of composition of materials and by use of high quality raw materials, the company has produced reliable gasketing products which always correspond to the latest state of technology.

"Champion" products are developed with the strong belief on the proven fact that the most qualitative gasket is cheaper than the work necessary for changing an improper gasket.

Gasket Selection
Gaskets must maintain a seal for an acceptable period against all of the operational forces involved and to achieve this, there are eight important properties which any good gasket should possess:

• The gasket should not be porous to the fluid being sealed.
• The gasket should compress into the imperfections on the flange to create initial seal on application of sealing force.
• The gasket should not show significant creep under the influence of load and temperature. Such flow will allow the bolts to relax, reduce gasket surface stress and cause leakage.
• The gasket should be capable of catering to slight distortion between the flanges.
• The gasket should withstand chemical attack from the media being handled.
• The gasket has to be easily dismantled after use.
• The gasket should be able to withstand effects of temperature of the confined media.
• The gasket should not cause corrosion of the flange faces.

Champion Asbestos fibre jointing sheets are manufactured on latest factory equipments and developed with the aid of research and scientific facts to take care of one and all of above factors combined with highly specialised technical knowledge of Engineers with experience of a life time. Our products meet with the increasingly exacting requirements in Engineering and chemical industries for contact gaskets on fixed sealing faces. Champion Asbestos fibre jointing sheets are manufactured to international quality standards, which our customers can depend upon. The operating temperature for Asbestos fibre jointing sheet material is related to the thickness selected. Thinner materials offer better temperature and pressure properties.

ZERO LEAKAGE CLEAN & EFFECTIVE
"Champion" PTFE Thread Sealant Tape, due to the special nature of the thread seal will be lasting and resistant to high temperatures and corrosive chemicals. The seal will not harden or become brittle but will remain flexible enough when the seal is opened for maintenance.

"Champion" PTFE Thread Sealant Tape can be used for various media from corrosive chemicals to water and gas to oil, in hydraulics and pneumatics.

Instructions for proper usage
Wind the tape by hand, using a constant minimal tension sufficient for the tape to take up the form of the thread. The tape should be wound in a helical fashion with a 50% overlap (as shown in the diagram) in the direction of the thread so that when the connection is completed the finishing end of the tape remains in position. The tape width should not exceed the length of the thread form.
