I went the welding store yesterday to buy some anti-flashback arrestors for a gas welder to go between the regulators and the hoses. They had some short arrestors that cost $16 and some long arrestors that cost $64. The owner did not know what the difference in the two was and said they did the same thing. Since one is 4 times the length and 4 times the cost of the other, I do not belive he is correct ; however, the packaging did not identify any functional differences. Does anyone know what the difference is besides size and price? Don
