  "id": "MLC-T-OAG-002550",
  "term": "No-go landing nipple",
  "field": "Oil and gas",
  "definition": "A type of landing nipple with an internal shoulder that provides a physical stop to prevent a flow-control device or running tool from passing through it. The corresponding lock mandrel has a matching no-go shoulder that lands on this restriction, providing positive depth location for setting the device. This design contrasts with selective nipples, which lack a restrictive shoulder and rely on a profiled key system for location.",
