Hakko B2506, Damper for FR-410/400, FM-204 and 472D Stations, Pack of 2
Hakko B2506 — Replacement Damper for FR-410 / FR-400 / FM-204 / 472D Desoldering Stations, Pack of 2
The Hakko B2506 (SKU: B2506) is an OEM replacement damper for Hakko FR-410, FR-400, FM-204, and 472D desoldering stations. The damper is a wear item in Hakko desoldering systems — it absorbs the mechanical shock from the vacuum pump piston and maintains consistent suction performance. A worn or damaged damper results in reduced suction, inconsistent desoldering, and increased pump wear. Replacing the damper at regular maintenance intervals restores full desoldering performance. Supplied in packs of 2.

Frequently Asked Questions
How do I know when the damper on my Hakko desoldering station needs replacement?
Common signs of a worn or failed damper include: reduced suction power, inconsistent solder removal, increased noise from the vacuum pump, or visible damage to the damper material. If your FR-410, FR-400, FM-204, or 472D station is not desoldering cleanly despite a clean nozzle and filter, the damper is often the cause. Hakko recommends proactive replacement at regular maintenance intervals rather than waiting for failure.
Is the B2506 compatible with all Hakko desoldering stations?
The B2506 is specifically designed for the Hakko FR-410, FR-400, FM-204, and 472D desoldering stations. It is not a universal damper for all Hakko products. Verify your station model before ordering. Contact MTE Solutions if you need a damper for a different Hakko desoldering station model.
How do I replace the damper on my Hakko desoldering station?
Damper replacement procedures vary by station model. Refer to the Hakko service manual or maintenance guide for your specific station (FR-410, FR-400, FM-204, or 472D) for step-by-step replacement instructions. The procedure typically involves accessing the pump assembly, removing the worn damper, and installing the new B2506 damper. Contact Hakko or MTE Solutions for service documentation if needed.
How often should the damper be replaced?
Hakko recommends replacing the damper as part of scheduled preventive maintenance. Replacement frequency depends on usage intensity — high-volume production environments may require more frequent replacement than low-volume repair shops. Refer to the Hakko maintenance schedule for your specific station model for recommended replacement intervals. Keeping a spare B2506 on hand minimizes downtime when replacement is needed.
