The Midland Haldex 9125X is an air brake relay valve designed for heavy-duty truck brake systems. Relay valves are a critical component in air brake circuits, responding to control pressure signals to deliver or exhaust air to the brake chambers faster than the foot valve alone can manage. The 9125X is also cross-referenced under part number EX9125X. If you need to verify this valve fits your specific brake system configuration, contact Pro Gear and Transmission and we will help confirm the correct application before you order.
A refundable core charge of $28.00 applies to this item and will be collected at checkout. The core charge is refunded upon receipt of your returned core, subject to its condition; customer is responsible for return shipping. Call us at (877) 776-4600 for details.
