THE ORID

A unique simple tool no larger than a pencil identifies O-Ring Composition eliminating downtime due to O-Ring failure. The ORID takes the guesswork out of parts assembly and chemical compatibility.

The ORID will indicate the material composition of 100,200,300 and 400 series O-rings of 60 to 80 Durometer, which are already known to be either Viton, Kalrez, Nitrile or EPDM. The O-rings must be within their rated shelf life and be unused and undamaged.

Handy Comparative Tester :

• Verify an O-ring at moment of installation

• Check for mislabeled O-rings

• Verify new O-rings

• Sorting Applications

• Differentiate between known O-rings that have become confused either in storage or on the assembly line

• Sturdy stainless steel tubular construction is safe to carry in tool boxes

• Pocket clip for easy access

Labeled Graduations :
The height of the first bounce identifies the O-ring :

• Highest graduation ...EP, ethylene propylene O-rings are compatible with most water based chemicals from  - 70ºF to +300ºF
• Third Graduation ...NITRILE. Also known as Buna-N. These O-rings are good for most plumbing applications from -30ºF to +225ºF
• Second Graduation ...KALREZ. Also known as perfluorocarbon, compatible with most aggressive chemicals from 0ºF to +600ºF
• Lowest Graduation ...VITON. This composition is also called fluorocarbon. VITON O-rings are generally compatible with most petroleum based liquids from -15ºF to +400ºF.

Precautions :

• Do not use for any O-ring applications other than those indicated above.
• Temperature extremes may alter readings
• The results obtained through the use of this device have been consistent and repeatable in our evaluations. However since a degree of user technique is required, we cannot be responsible for specific results.
• Do not use to identify flat gasket material
• Consult the factory for special applications
