Old SMC Solenoid legal???

SMC solenoid SY3240-5LOU

We have been using them for years but noticed a rule about 1/8" NPT.

Not sure if these conform to that rule.

Thanks

From a little web surfing on that model it looks to be legal.

It shows on the manual that the input and output ports on that paticuale model are 1/8"

You can find a copy of the manual for that solenoid series here

Look on page 7.

Good luck this season!
