Product summary

SEAL-LOCK® BOSS is a threaded and coupled casing connection designed to be cost competitive with API Buttress.

BOSS utilizes a patented hooked thread design for sealing and a unique pin-to-pin torque shoulder to provide enhanced compressive loading.

A rugged thread form and advanced connection geometry results in deep stabbing and quick make-up without cross threading. High performance-cost effective. A negative load-flank thread and advanced connection geometry results in smooth trouble-free running.
