Quick-Install Pressure Test Fittings

NPT Male Inlet Plug |
Thread these fittings onto your testing equipment by hand for a secure connection in testing applications—no tools, tape, or sealant required. Use them with gauges and other equipment as a temporary connection. When pressure is applied, the O-ring on the outlet presses against the testing equipment, creating a tight seal.

High-Vacuum Sights for Quick-Clamp Fittings
 |  |
Sight Shown Assembled with Tube Fitting, Ring, and Clamp (All Sold Separately) |
Designed with quick-clamp (KF) connections, these sights connect to a port on a high-vacuum chamber, so you can monitor what's happening inside. A sleeve seals the glass window to the body of the sight to prevent leaks. To connect to your chamber, you'll need a clamp and a ring (sold separately). Not for use in pressure applications.

Ultra-High-Vacuum Flanged Sights
 |
Add a window to your ultra-high-vacuum system. With a pane of glass sealed inside an ultra-high-vacuum CF flange, these sights bolt onto vacuum chambers, tee fittings, and manifolds. Use a copper gasket (sold separately) to create a seal. Not for use with pressure. To illuminate dark interiors, attach an optional light to the flange with set screws.
