BW-20 Clear Window Reflector
|
|
Designed for multiple use, these gauges are made for insertion in tapped els, tees or other NPT fittings and are easily installed and removed with a wrench. Also available with straight machine threads and "o" ring gasket. Recommended maximum pressures listed for styles BW-10 and BW-20 allow safe margins for variations in application and installation. Maximum recommended temperature is 250 Deg. F. Not for air service. Same as BW-10 with the addition of a white reflector to show oil level more clearly. Not for air service. |
