These silicone parts can be used in trucks, recreational vehicles, boats, or anything else with an engine.

Please note the following when you order silicone parts online. Some vendors have started counting the layers of silicone instead of the layers of reinforcement when talking about the ply. For example, a 3-ply reducer has four layers of silicone plus three layers of reinforcement fabric. Some vendors might incorrectly call this a 4-ply reducer because of the four layers of silicone. All of our silicone parts are now of Genuine 4-Ply construction - that's 5 layers of silicone plus 4 layers of reinforcement for 9 total layers!

Genuine 4-ply Silicone (5 silicone layers plus 4 reinforcement layers = 9 total layers!)
