The 2BC Series of multi-tube connectors is unique because it has integral push-to-connect fittings, and doesn't require any other attachment. This eliminates the cost of purchasing additional fittings and the labor to install them. Four line configurations are offered: 10 and 12 1/8-inch, 8 1/4-inch, and 10 4-mm OD tubes. Reported to be suitable for most types of soft tubing, the connector is rated to 125 psi and is made of aluminum, nickel plated brass, Buna-N, and EPDM. Although, other materials and configurations are available.

Cable Sensor, a presence, motion, and limit sensor for hostile environments, is designed to be immune to the effects of extreme temperature, corrosive spray, powders, and abrasive dust, and can be used in liquid submersion applications. The device uses a stainless steel cable to contact a moving object and transfer that motion to the control electronics. System sensitivity is 0.1 inch, dynamic range is greater than 72 inches, and sensed-area capacity is 0.1 inch to 500 ft.
