Exhaust Pressure Fittings for Glow Engines
A pressure fitting taps exhaust or muffler pressure to feed the fuel tank, helping maintain a steadier fuel supply as the tank empties. This category collects exhaust pressure fittings and related parts for glow engines and their mufflers.
Bolt-On Fittings
Bolt-on pressure fittings are offered in several thread sizes so you can match the tapped hole in your muffler, including 4-40 fittings from Fox, a 6-32 bolt-on fitting, and an 8-32 bolt-on fitting from Du-Bro. Choosing the size that fits your muffler avoids reworking the threads.
Muffler Nipples and Thru-Hole Options
For specific engines, the Magnum XL muffler nipple fits a range of .15 to 1.20 size mufflers, and the Mac's thin wall thru-hole pressure fitting provides an alternative mounting approach where a bolt-on will not work. A secure, leak-free fitting is what lets muffler pressure do its job of feeding the tank consistently.
