Helpful Guide Tube Chart

There are easily over 50 different kind of Pratt & Whitney PT6 engines out there.  Which guide tube is appropriate for the one you’re in charge of maintenance for?  Pratt & Whitney reps will often suggest mechanics refer to their guide books and instruction manuals.  Many of these are the size of large city phone books!  Most mechanics and safety inspectors don’t carry every manual with them at all times, not even the digitized versions.

Sometimes, it’s not the mechanics or inspectors familiar with the equipment who make the purchases.  What is a purchasing agent to do, with no practical knowledge of what they have been instructed to buy?

Below, is an abbreviated Guide Tube Chart referencing which PT6 engines are an appropriate match for which guide tubes we sell.  Not every Pratt & Whitney engine or guide tube is listed.  Only those relevant to the guide tubes we keep in stock for sale.  Even so, we hope our customers will find this helpful!
