Description

Product Overview

The National 370219A wheel seal is a precision‑engineered component designed specifically for the Dexter FWRW series of hydraulic and pneumatic equipment. Constructed from high‑grade black rubber, this round lip seal delivers exceptional resistance to abrasion, chemical exposure, and extreme temperature fluctuations ranging from -40°F to 225°F. Its unitized design integrates a spring‑loaded main lip with patented SURE‑LOCK ribs, providing a secure, point‑contact seal that minimizes shaft interference while protecting the bore from wear. Weighing just 1.6 ounces, the seal is lightweight yet robust, featuring a painted exterior for added durability and visual identification. The product carries the manufacturer part number 370219A and complies with industry standards for oil seals, making it a reliable choice for demanding industrial applications.

Usage

This wheel seal excels in environments where reliable shaft sealing is critical, such as in hydraulic pumps, pneumatic actuators, and heavy‑duty machinery that operate under high pressure and temperature extremes. Its temperature‑resistant rubber formulation ensures consistent performance whether the equipment is exposed to sub‑freezing conditions or heated to over 200°F. The seal’s design reduces friction, extending the life of rotating shafts and decreasing maintenance intervals. It is ideal for technicians and engineers seeking a dependable seal for both new installations and retrofits, providing a seamless fit for the Dexter FWRW model line when the Amazon Confirmed Fit criteria are met.
