Failure to install proper dielectric flange seals or O-rings may cause process leaks, which can result in
death or serious injury. Only use dielectric flange seals or O-rings designed for the specific
connector.

Stabilized and non-stabilized connector installation
1. Verify equipment is rigid and secure to support weight of connector assemblies.
2. Remove all protection caps from the threaded connections.
3. Verify sealing surfaces and threaded connections are free of dirt, dust, or debris.
4. Wrap PTFE tape on NPT threads, ensuring start of thread is completely covered.
5. Using a 1
at 65 ft-lbs (90 N-m).
6. Repeat steps
7. Check the height of the outlet flanges and ensure they are aligned at the same height to allow
proper installation of the manifold. If necessary, adjust the connectors to the proper height.
8. Align the stabilizing foot (if present) to the equipment in the desired position, based on a flat or
round surface.
9. Tighten the tension hex nut over the stabilizing foot to 110 ft-lbs (150 N-m) using a 1
10. Place PTFE gaskets in the outlet flange grooves of the connectors. Insert the four bolts with washers
into the connector holes or slots and hand tighten into manifold process flange.
