O-seal valves

O-Seal system valves and fittings from this company are rated for heavy-duty liquid or gas service. They are designed to allow operators to change-out valves and other components for maintenance with the turn of a union nut. Operators can also install, remove, rotate, or reposition pipe section or valves without springing or having to cut the line. The system's reported leakproof reliability is the result of two flat-faced fittings joined with a resilient O-ring-incorporated into a close tolerance groove that actually utilizes line pressure for a tight seal.

Miniature pump

The 7006 miniature oil-free pump produces up to 3 bars of pressure and vacuums to 85% single stage (98% dual stage) in a 123x46x78 mm package. It features a totally enclosed console that reportedly reduces its noise signature considerably. With a permanently lubricated ball bearing to prevent air contamination, the 7006 pump is ideal for a variety of special market applications, including environmental, scientific, and medical.
