Safety Valve Landing Nipple

STAR Safety Valve Landing Nipples are used to accommodate wireline retrievable sub surface safety valves. These nipples have a locking recess and a hydraulic communication port located between the two polished bores. This nipple features an integral control line connection port which operates Sub Surface Safety Valve. The nipple is a one-piece construction, manufactured from bar stock and contains the highly successful, field-proven lock profile.

Features and Benefit
