MAX-COUPLING PART NUMBERING SYSTEM
  Part No. AF15V-06  (ISO A socket, poppet valve, NPTF thread, Vinton seal, 3/8" size)  
A = Series Part series
F = Half or pair F = socket, M = plug, C = complete pair (assembled)
1 = Valve type 0 = free flow, 1 = poppet, 2 = ball, 3 = connect-under-pressure (type 1), 4 = c-u-p (type 2)
* For flat face couplings, 1 = standard flow version and 2 = high flow version
5 = Thread type 0 = BSPP (parallel), 2-4 = metric male 24 degree threads, 5 = NPTF, 6 = metric female, 7 = UNF, 8 = BSPT (tapered), 9 = SAE (O-ring boss)
V = Special seal V = Vinton, K = Kalrez, F = Fluorosilicone, E = EPDM, N = Nitrile, Neo = Neoprene
* This position is used only when deviating from standard seal specifications
06 = Thread size Expressed in 1/16ths of an inch for NPTF threads
