Description
Product Overview
The Noa Store Plastic Outer Member Cap is a precision‑engineered component designed to fit a 2.5 inch diameter outer member housing commonly found on trailer and truck brake assemblies. Crafted from high‑quality black plastic, the cap provides a robust barrier that protects the underlying brake components from dust, moisture, and mechanical impact. Its modern design incorporates a twist‑snap mechanism that securely locks the cap in place while allowing effortless removal when service is required. The cap’s dimensions—approximately 15.75 x 14.17 x 15.75 inches—ensure a snug fit without adding unnecessary bulk, and its lightweight construction (0.317 ounces) minimizes any impact on overall vehicle weight. This product is a standard issue cap compatible with UFP brake actuators and aligns with part number #21 on the UFP parts list schematic, guaranteeing seamless integration with existing brake systems.
Usage
Designed for both trailer and truck applications, this outer member cap excels in environments where reliability and ease of maintenance are paramount. Whether operating in rugged construction sites, long‑haul freight routes, or agricultural settings, the cap safeguards the brake housing against contaminants that can degrade performance. Mechanics and fleet technicians will appreciate the cap’s quick‑release feature, which allows rapid access to the reservoir plug and master cylinder for routine inspections, fluid changes, or emergency repairs. Its universal fit for 2.5 inch diameter housings means it can be deployed across a wide range of brake models, reducing inventory complexity and simplifying part selection for service departments. The cap’s durable plastic composition also resists UV exposure and chemical corrosion, making it suitable for outdoor storage and harsh weather conditions.
