Assembly procedure This component is designed to ease the assembly of the manifold to the differencial manometer or transmitter (54mm; 2 1/8" distance between connections). First, thread the male end (5) to the transmitter inlet, and thread the sets of male end 1/2" NPT, rings and nut to the manifold outlets. Then, bring face to face and insert the ends into the nuts. Check both parts are parallel. Finally, tighten the nut manually, fasten the body of the connector with a spanner, and with another spanner tighten the nut again 1 turn and 1/4. This will result in a perfectly sealed and safe connection between the manifold and the differential transmitter.
Packaging
All TECVAL ADF couplings are supplied packed in polyethilene airtight bags. Everything is 100% recyclable.
