5TH WHEEL SLIDING COIL 54

It provides a flexible, reliable air connection between the tractor and the sliding fifth wheel air cylinder, allowing the fifth wheel to slide fore and aft without kinking or tangling the air line. The coiled design with an extra-long strain-relief spring helps prevent kinking and extends service life, while the brass end fittings resist corrosion. It is commonly replaced when the original coil becomes brittle, cracked, leaking, or permanently stretched.
