The Hex HB52 Bleed Tee is ideal for modernizing outdated, non-bleed gauge installations. During instrument maintenance, simply thread the HB52 into the outlet of an existing block valve. An instrument is then threaded into the HB52 outlet to complete the installation. A second 1/2" side outlet accommodates a gauge or tube fitting for a remote auxiliary instrument. Bleed-off is simple - a turn of the handle directs flow through the discharge tube.
