The Series MD/MN is a compact, lightweight, economical diaphragm seal. The upper and lower housing, as well as the diaphragm, are type 316 stainless steel - all welded together making a one piece integral unit, ideally suited for those applications where space is a factor.

The use of a hermetically sealed, liquid filled pressure gauge in conjunction with either a MD or MN seal protects the indicating gauge
from both the process medium and atmospheric conditions, as well as reduces pointer fluctuations due to vibration and pulsation.

REMOTE MOUNTING: Stainless Steel Plain Seamless or Armored Capillary with Stainless Steel Fittings can be provided
for remote mounted applications. Fittings are available in 1/4" or 1/2" NPT.
