Gas springs and tailgate struts need a measured amount of oil to lubricate the seal and give end-of-stroke damping. Inconsistent filling shows up in feel and service life. TD-YL506 combines automatic feeding with precision dispensing so every cylinder is filled under the same conditions.
End closing (TD-31040) → inner oil grooves (TD-627) → oil filling (TD-YL506) → press-fit & folding (TD-724 / TD-AT155) → end fitting (TD-91528). See How gas springs are made for the full process.
