It uses 3/4-16 ORB-08 threading for secure sealing and swiveling inlet fittings for clearance. The telescoping centerline adjusts from 7.700 to 13.450 inches. ORB-10 inlet/outlet ports accept AN adapters, two 1/8 NPT gauge ports are provided, the 1.056/.806 ID bore supports high flow, and a Type II bright-dip black anodized finish protects the unit.
