Velvac 038005-1 Support Spring 28 In. Pack of 5

SKU CH-H3EV-98QJD

Zinc-plated 28-inch support springs for air brake hose, sold in packs of five

  • ASTM A227 standard ensures consistent material quality
  • Zinc-plated finish resists corrosion on air brake systems
  • 28-inch length fits standard hose support requirements
  • Pack of five covers multiple installation points
  • Gold colour allows quick visual identification during inspection

Application fit

Velvac 038005-1 Support Spring is a zinc-plated steel coil designed to protect air brake hose on commercial vehicles. The 28-inch length covers extended hose runs where vibration and road debris cause premature wear. Fleet maintenance teams and heavy-duty truck owners use these springs to meet ASTM A227 material requirements on tractor-trailer combinations.

Installation notes

Each spring slides over the hose before the fitting is crimped, so no special tools are required beyond standard hose assembly equipment. The gold chromate finish resists corrosion during fitment, but installers must verify the hose outer diameter matches the spring bore to prevent binding. Over-stretching the coil during positioning can reduce its protective coverage.

Critical specification

The 28-inch overall length is the single dimension that determines whether this spring will shield the full exposed section of hose on a given axle configuration. Measure the hose run between frame brackets before ordering; a shorter spring leaves the ends unprotected while a longer one cannot compress enough to fit. The pack of five suits a typical dual-axle service job.

Questions about this item

How do I verify the 28 In. support spring is correctly installed on my air brake hose?

The zinc-plated gold spring should sit evenly along the hose without gaps or kinks, and the hose must not sag or rub against surrounding parts when the vehicle moves.

What does the pack of 5 include and what else is needed for installation?

Five 28 In. zinc-plated gold support springs are supplied; mounting brackets or fasteners are not included and must be sourced separately.

When should I choose the 28 In. ASTM A227 spring over other lengths?

Select this version when the air brake hose run measures approximately 28 inches and the application requires the ASTM A227 wire standard.
