2300/2300EL Slack Reducing Coupling

Popular with tanker fleet customers, the 2300 slack reducing coupling can be used throughout the industry. As with all 2000 series couplings, the 2300 is made from Premalloy, offers unsurpassed latch strength, and can be operated with or without an air service chamber. The 2300 is available with our Extended Life (EL) latch option. Engineered latch lubrication points deliver lubricant directly to the pivot points resulting in smoother and more consistent latch performance. Each coupling has a maximum gross trailer weight of 100,000 lbs. and 60,000 latch capacity for heavy-duty applications.
