Overview

The Dorman 493-100 is a set of five rubber cooling bypass caps. They feature a 5/8 inch female push-on fitting and a black and natural color.

Dorman cooling bypass caps are ideal for sealing off coolant lines and hoses. They provide a tight fit to prevent leaks and are constructed from durable, heat-resistant vinyl. These caps are also suitable for capping lines and hoses during testing. They are sold as a set of five. Some parts may not be legal for use in California or other states with similar laws.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
