B & T Check Set Tool Specifications Sheets
The B & T Check Set Tool is used to insure that the B & T X Locks and B & T R Locks have been properly set in the appropriate landing nipple. Once the B & T Check Set Tool has been successfully run with either a B & T X Lock or B & T R Lock, its shear pin will be sheared.
If the shear pin in the B & T Check Set Tool is sheared, then the lock has been properly set into the corresponding R Landing Nipple or X Landing Nipple.

B & T D Lock Specifications Sheets
The B & T D Lock is used to land and lock in any collar recess of API collared tubing. Once the packoff element has been mechanically locked in the set position, pressure can be held from above and below. It can be used with pump thru plugs, positive plugs, safety valves, standing valves, and packoffs.
Packoff elements are available in a full range of rubber material to meet well-specific conditions. The standard material is NBR. Consult the Elastomer Chart to see all possible compounds.

B & T R / RN Lock Specifications Sheets
The B & T R Lock is a selective lock that can be installed in R Landing Nipples. It is used in heavier weight tubing due to higher well pressure. The B & T R / RN Lock's packing mandrel allows it to hold pressure from either above or below and its keys engage a profile in the R Landing Nipples.
The B & T RN Lock is the No-Go version of the B & T R Lock. The keys have an angled shoulder, designed to fit into the bore restriction of the RN Landing Nipple.
All B & T R / RN Locks come standard in 9 Chrome. Other materials are available on request.
Assemblies with different packing configurations are available; however due to different material densities packing will not always have the same stack height. When ordering redresses with non-standard packing, please call to ensure that you order the correct number of pieces.

B & T S Locator Specifications Sheets
The B & T S Locator is made up to the bottom of the B & T S Lock to set in B & T S Landing Nipples. By changing the position of the keys, the operator may set the lock in one of five different nipples in the tubing string. The spring loaded keys locate the corresponding landing nipple and prevent the lock from traveling out of the bottom of that nipple. Once this is accomplished, the lock would hold pressure from below.
Please specify what position keys are required when ordering.

B & T S Lock Specifications Sheets
The B & T S Lock is used in conjunction with the B & T S Locator to lock into the polished seal bore of the B & T S Landing Nipple. It can withstand pressure from above and below. It can be used with pump thru plugs, positive plugs, standing valves, and safety valves.
The standard material for the B & T S Lock is stainless steel. Consult the Vee Rings to ensure that the proper packing is ordered.

B & T W Lock Specifications Sheets
The B & T W Lock is used in wells that are not equipped with landing nipples during completion. They are attached to the wall of the tubing and during the running procedure, its element is expanded to seal against the tubing wall. It can only hold a differential pressure from below.

B & T X / XN Lock Specifications Sheets
The B & T X Lock is a selective lock that can be installed in X Landing Nipples. It is used in standard weight tubing. This lock uses keys to engage a profile in the B & T X Landing Nipple and an integrated packing mandrel that allows it to hold pressure from either above or below. This lock can be used in conjunction with pump thru plugs, positive plugs, standing valves, and safety valves.
The B & T XN Lock is the No-Go version of the B & T X Lock. The keys have an angled shoulder, designed to fit into the bore restriction of the XN Landing Nipple.
