The Kleinn Model 30202 is a premium steel-braided pneumatic leader hose engineered to handle the high heat and pressure generated directly by your onboard air compressor. Featuring a heavy-duty, corrosion-resistant stainless steel braided outer jacket that protects the internal line from abrasion and kinking, this universal 18-inch hose is designed with a 1/4" NPT connection on both ends. It comes equipped with a pre-installed, heavy-duty inline check valve to prevent high-pressure air from leaking backward through the compressor pump when it is turned off, ensuring a reliable, airtight seal and maximizing the efficiency of your entire pneumatic system.
