Air Conditioning O-Ring - Priced Each - 13.8mm

Product Details

A malfunctioning A/C system might not hurt your lap times, but sweating out a summer track day or a long tow to the grid in a roasting cabin absolutely saps your focus. If your BMW’s climate control has lost its chill, the culprit is often a tiny, flattened O-ring hiding at a line junction. Keep your cabin temperatures regulated with this high-durability Febi Bilstein Air Conditioning Line Seal Ring.

Engineered to drop seamlessly into the high-pressure and low-pressure line joints found across numerous BMW platforms (replacing OE part number 64538375742), this is not your average rubber seal. It is molded from advanced, heavy-duty green HNBR material designed to handle the elevated under-hood temperatures and high-vibration conditions typical of performance driving. When building a dual-purpose street/track machine or simply bulletproofing your daily driver, don't overlook the small details.

Key Features & Benefits:

• Direct BMW Integration: Direct swap for factory part number 64538375742 across E-chassis, F-chassis, and modern platforms.

• Track-Proven HNBR Build: Withstands high thermal stress and won't swell or tear when subjected to synthetic compressor oils.

• Restores System Pressures: Eliminates the slow, hard-to-find refrigerant leaks that trigger low-pressure safety cutoffs.

• No-Brainer Toolkit Addition: An incredibly inexpensive insurance policy to throw into your garage toolbox before cracking open your engine bay.
