Abstract
A tubular adapter is formed by a wall, the wall having a hole formed therein, and a gas sampling tube extends through the hole. The respective diameters of the hole and the tube are sized to produce a tight sealed connection therebetween but permit adjustment of the tube in the hole. The sampling tube has a sampling end thereof located within the tubular adapter, and the sampling end has a radially enlarged or flanged portion which is larger than the hole, whereby the sampling tube may be adjusted in the hole but may not be withdrawn.
