Standard (A250-SE), Long (A250-LE) and Flattening Reef (A250-FE) Cylinders of a specific Size use all the same components except for the Tube and Piston Rod.
To determine which Size Cylinders you have, Measure Tube and Piston Rod OD, and See: Product Specifications – A250 Standard Cylinders.
14A, 15ANewer A250 Cylinders feature recessed Pin holes for use with shorter Spiral Ring Clevis Pins, eliminating snag points and reducing weight.
