Central Plastics Company
Problems solved by
Jock O-Ring Sealing Gaskets
| The
Problem: |
Leaking
Flanges. |
| The
Solution: |
Use high energy
O-ring elastomers which maintain constant sealing force. This sealing element
encapsulation prevents gasket blowout, and the high quality retainer and seal materials
eliminate fluid permeation. |
| The
Result: |
Positive Seals
and Zero Environmental Leakage. |
| The
Reason: |
Jock O-Ring
Gaskets. |
| The
Problem: |
Catastrophic
Fire Failure. |
| The
Solution: |
Attain complete
contact of flange and retainer permitting only micro-exposure of seals to service fluid
and environment. |
| The
Result: |
PLongest Fire
Life of any Insulating Gasket. |
| The
Reason: |
Jock O-Ring
Gaskets. |
| The
Problem: |
High
Maintenance and Installation Costs. |
| The
Solution |
Achieve a
positive seal utilizing the elastic memory of the confined seal. This insures zero ASME
"M" and "Y" factors, producing reliable seals without tremendous bolt
loads. Undamaged insulating washers mean fewer shorts. |
| The
Result: |
Fewer Service
Calls due to leaking and shorting flanges. |
| The
Reason: |
Jock O-Ring
Gaskets. |
| The
Problem: |
Mismatched,
Misaligned, and damaged RTJ Flanges. |
| The
solution: |
Use a narrow
self-energized seal capable of withstanding high fluid pressure. |
| The
Result: |
Maintenance
Versatility and Positive Sealing in difficult situations. |
| The
Reason: |
Jock O-Ring |
Overcoming Mismatching &
Misaligning Problems
