The HAKKO B5077 O-Ring replacement part for the HAKKO FR-410 and FR-400 soldering irons. It is a rubber O-ring that seals the vacuum outlet of the soldering iron, preventing air from entering the vacuum pump. This helps to maintain the vacuum pressure inside the soldering iron, which is necessary for its proper functioning. The O-ring is made of a durable material, such as silicone or nitrile rubber, and is resistant to heat and chemicals. It is important to regularly check and replace the O-ring to ensure that the soldering iron is functioning properly and to prevent leaks.
