Petcock Slide Type For Thiefs
Manufacturer: W.L. Walker
Petcocks are recommended for putting the sample directly into the centrifuge tube, per the API Manual of Petroleum Measurement Chapters 8.3 and 10.4. This petcock is easy to install and use. It does not require threads in the barrel and has a full 1/4 inch unrestricted opening. Just push in on the slide part, collect the sample, and release. The installation is simple. Drill a 1/2 hole in the barrel of the thief at the location or locations you want. Be sure to remove any burrs. (If drilling a plastic barrel, drill a pilot hole before you drill the 1/2 hole and use a drill bit appropriate for plastic.)
