| BLADDER |
| Bladders are manufactured in-house to control the material blending, molding, and critical seam assembly and curing processes. It is widely accepted that OilAir
Hydraulics bladders are the highest quality bladders in the industry. Bladders are offered in four different standard compounds to suit a variety of fluids and operating temperatures. Special compounds are available for unusual or severe applications. |

| BLADDER STEMS |
| All Surge Arrestors are fitted as standard with two-piece bladder stems with replaceable gas valve cartridge for ease of serviceablility. This allows for the gas valve to be replaced separate from the bladder. |
