Limitations & connection constraints

  • This record covers the ETS EC 150/3 EQ-Plus, item 576326; do not extend it to another model or package without checking its documentation.
  • ID/OD is UNKNOWN: the source labels a connection diameter without specifying the measurement type.
  • Adapter interface dimensions, taper, locking geometry and vacuum-side fit remain UNKNOWN. No retailer product is a verified fit from this specification alone.

Before you buy

  • Matching the port diameter alone does not guarantee a complete, sealed, or compatible fit. Confirm taper, wall thickness, locking tabs, thread, shape, and material before buying.
  • Verify whether each measurement is inside diameter (ID) or outside diameter (OD) before purchasing. Nominal labels are search aids, not fit guarantees.
