Similar probes can have modifi odific cations, e.g. Ÿ
A & AC AC probes probes cann cannot ot be be used for the same operation, an AC AC probe probe has no internal thread th read to acc accept a prong Ÿ
An M1 Probe has a telltale shear pin where where an M prob probe e has not. Ÿ

C1 can be used to run run the the S selec sel ectiv tive e lock loc k with with th the e up facing facing dog dogss trailing Ÿ
unn ng oo s Bake akerr M pu pulllling ing tool tool used to run and and pull pull several locks Ÿ
E, M (loc (locks) ks) and and B (safety valve) loc locks ks can can be run using the the M pulli pulling ng tool tool Ÿ
With this this tool th the e probe is also also used to set the th e devic device e Ÿ
E.g. when an M1 E.g. M 1 probe is used to set devic dev ices, es, the probe probe has a shear shear pin to indicate indic ate correc orrectt sett setting ing Ÿ

a er urs rse et equ pment Standard equipment equipment did not meet meet pressur pressure e rating rating needs of the industry Ÿ
New system need needed ed henc hence e Surset Surset was was developed
Ÿ
New nipples dev developed eloped that that inc included luded press pressure ure ratings
Ÿ
Retain F and R nogo positioning
Ÿ
A <10 <10K K, H 1010-15K and V >1 >15K
Ÿ
New nipples becam became e AF, AF, HF, HF, VF, AR, HR and VR VR
Ÿ
a er urs rse et equ pment Locks made to match nipples hence AF went into an AF nipple, nipple, of VR lock lock matc matched hed a VR nipple nipple Ÿ
Only two equalizing equalizing de dev vic ices es use H – pron prong g and M – melon (sometimes known as R) Ÿ
Ÿ
One running tool (model A) to run all locks
Ÿ
Can be pulled with Baker M (Otis GS)
