ELSOON XF-302A Reverse Flow Solenoid
Best for: Dexter Tie Down Engineering Brake Actuator users who need a compatible reverse flow solenoid. This ELSOON model is designed to fit the XF-302A specification and can be integrated into drum brake systems where reverse flow control is required. Choose this if your trailer uses Dexter components and you want a direct compatibility fit. A potential limitation is that installation relies on matching the XF-302A specification exactly; verify your actuator model before purchase.
UFP Reverse Lockout Solenoid After 2020
Best for: Utility applications needing a durable iron-bodied solenoid with clear reverse lockout functionality. This model emphasizes reliable construction and compact design for easy integration. Best for users who back up frequently and require a robust, straightforward lockout feature. Limitation: designed for general utility systems rather than a specialized OEM actuator; confirm compatibility with your specific valve fittings.
BUYMACHINERYPARTS 4748800
Best for: Dexter Titan Dico 60 surge actuators requiring a reverse lockout replacement. This 12V solenoid valve supports common fittings (3/8″ Female, 1/8″ Male NPT, 24 UNF) and is pitched as a drop-in option for compatible OEM numbers (068-213-00, K68-213-00). Choose this if you need a direct OEM-referenced substitute. Limitation: verify connector types and port sizes match your current setup to avoid leaks or misfits.
Solarhome Solenoid Valve T4748800
Best for: Titan brake actuators with reverse lockouts needing a compatible valve. Solarhome’s T4748800 is positioned for Titan systems and emphasizes compatibility with reverse lockout configurations. Choose this when your setup centers on Titan actuators and you want a purpose-built valve. Limitation: may require exact torque and sealing specs to prevent leaks in high-vibration trailer environments.
Czomoizc 4748800 / 068-213-00
Best for: Titan brake actuators with reverse lockouts requiring a converter-friendly valve. Czomoizc’s dual-number reference (4748800, 068-213-00, K68-213-00) makes it a flexible choice for mixed fleets or when OEM references differ between vehicles. Opt for this if you need broad compatibility across Dexter Titan and Titan Dico actuators. Caution: confirm exact port sizes and threaded connections before purchase to ensure a leak-free fit.
Buying Guide
What should you consider when buying a trailer reverse lockout solenoid? Start with compatibility: verify actuator make and model (Dexter, Titan, Dico 60, etc.) and confirm port sizes (such as 3/8″ or 1/8″ NPT) and electrical requirements (12V is common). Next, assess durability: the iron-bodied designs generally withstand harsh environments better than lighter materials. Consider installation ease: look for compact designs, clear mounting options, and kits that include mounting screws and O-ring seals. Evaluate lockout effectiveness: ensure the solenoid provides a dependable reverse flow or blocking function to prevent accidental backing. Finally, assess availability: choose options from reputable brands with readily accessible replacement parts and documented compatibility with your trailer system.

Frequently Asked Questions
- What is a trailer reverse lockout solenoid used for? It prevents brake actuation when backing up, reducing the risk of accidental engagement.
- How do I know if a solenoid fits my actuator? Check the actuator model, port sizes (NPT or UNF), and mounting compatibility listed by the manufacturer.
- Are all reverse lockout solenoids 12V? Many are, but always verify the voltage rating on the product page to match your trailer’s electrical system.
- Can I mix brands for replacement parts? Compatibility depends on port sizes and valve geometry; mixing brands is possible only if specifications align.
- What maintenance is recommended for reverse lockout systems? Inspect seals, O-rings, and mounting hardware periodically; replace worn components to prevent leaks and misfiring.
- Do these solenoids require special tools for installation? Typically a basic toolkit suffices, plus thread sealant or O-ring lubrication as recommended by the maker.
