TRACEPAK® and STACKPAK™ instrument impulse connection tubing bundles as well as process and emissions analyzer sample transport bundles incorporate industry leading innovations such as TrueTube® sample transport tubing and SensorTube® temperature control. Eliminating analyzer response delays that were routine and accepted and simplifying trouble prone installation of temperature control solutions.

VIPAK®, HEATPAK® and FLEXPAK® instrument enclosures provide winterizing and temperature maintenance for field mounted process instruments, manifolds and fittings. VIPAK is an overall enclosure available in three configurations and fifty sizes. Rigid ABS and fiberglass outer shells with molded in place polyurethane insulation protect instrumentation in ambient conditions as low as -70°F/-60°C. HEATPAK and FLEXPAK options protect only the process wetted portion of the transmitter and manifold.

SADDLEPAK® is a modular support system for field mounted instruments. Solutions are available from traditional floor mounting to tensioned cable mounts that close couple instruments to process piping. The 9-mil zinc coating is three times thicker than hot dip galvanizing and provides superior corrosion protection.

O'Brien MJ® polymer coated tubing and STRUT-RAK™ alternative to cable tray are designed for the demanding requirements of offshore applications where space and weight savings are as important as the corrosion resistance of small-bore tubing systems.

O'Brien SERVICESSM provides factory installation and design review for all industry applications.
