no problem. Id probably grab a brass one instead of plastic though if you can find one. If you're ordering online, http://www.amazon.com/MettleAir-129-6-4-Reducer-Splicer-Fitting/dp/B00CIX3TSW/ref=pd_sim_86_9?ie=UTF8&dpID=31ncVZg4j%2BL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=0J0NAVHYZS35X3G6TXB9
or if not, gas fitting shops, plumbers etc will have them. Id imagine they're around at big boxes in the states (im not from the US)
