Type AT is rated at 250 psi

SAE-J1532 -- This SAE Standard covers four types of hose for use with 
automatic transmission fluid: A, B, AT, and BT. Type A and Type B are 
for use within a temperature range of -40 to 125 degrees C (-40 to 257 
degrees F) while types AT and BT are for use within a temperature range 
of -40 to 150 degrees C (-40 to 302 degrees F). Recommended maximum 
operating pressure for Type A and Type AT hose is 1.7 MPa (250 psi) 
while recommended maximum operating pressure for Type B and Type BT hose 
is 1.0 MPa (150 psi). The lower pressure (Types B and BT) hose is for 
auxiliary cooler applications only. The reference fluid for tests 
requiring the use of automatic transmission fluid shall be Dexron-II 
E/Mercon or equivalent. -- http://www.sae.org/technical/standards/
