Its funny you say that because man years ago the company I worked for bought a Mustang chassis dyno with a 5 gas analyzer to the tune of $25k. The Gas analyzer had a finned cooler where the the hose to the analyzer sniffer attached. The cooler had flared fittings and the wand had a male NPT. They wrapped the crap out of the NPT with Teflon tape and shipped it to us. Pretty sleezy for the price and the fact the analyzer would have false readings if there was a leak anywhere between the sniffer and the gas analyzer system.
