Large Bore

DOWNHOLE HIGH TEMPERATURE / HIGH PRESSURE SLIP RING

Model 303 Oilfield-Downhole Large Bore Slip Ring

The Model 303 large bore is a family of electrical slip ring products designed specifically for the extremely harsh high temperature and high pressure (HTHP) oilfield-downhole environment. These products are designed and tested to operate at temperatures of up to 200°C and pressures of 25,000 psi (1700 Bar), and are generally configured for an oil-filled environment. Contact our oilfield - downhole slip ring experts for details.

Features
