FASTER female aluminum dust cap DN38 size 8 86004200 TM112S

Main protective dust plug for heavy-duty female hydraulic quick release couplings, manufactured by Faster, commercial part number 86004200 (original OEM reference: TM112S / TM 112 S). Professional protective component belonging to numerical series 8, specifically engineered for ultra-high-flow couplings with a nominal size of DN 38 (1.1/2"). Machined from solid, high-grade aluminum, it offers exceptional mechanical resistance against impacts, heavy-duty mechanical stress, and harsh operating conditions typical of heavy agricultural and industrial machinery. This protective accessory is essential to shield the female coupling internal cavity and precision sealing surfaces from dirt, mud, dust, moisture, and debris during equipment disconnection and storage. Regular use of this dust plug prevents hydraulic circuit contamination, significantly extending the service life of internal seals and quick-coupling components.
