Quick Coupling Half
Mack

As an essential half of a two-piece quick-connect system, this Quick Coupling Half offers dependable, fast coupling for hydraulic lines in heavy-duty trucks. The precision-formed housing, resistant to heat and corrosion, pairs with the matching male half to form a secure, leak-tight pathway for fluid transfer. The design emphasizes ease of use in cramped engine compartments or roadside service where efficiency matters; a simple push-to-connect action reduces tooling time and exposure to contaminants. Sealing is handled by a high-quality O-ring and mating surface that maintain integrity under pressure, even in dusty environments. Replacement is straightforward, with visual cues signaling proper engagement to prevent accidental disconnections. When paired with the correct counterpart, it supports consistent flow characteristics and long service life in demanding applications such as fuel, lubrication, or hydraulic circuits. This part is typically stocked for quick swap during maintenance or repairs. Available through Source One Parts Center.
