What You Don't Know About Hoses Can Kill You...

Many mechanics are not trained on how to correctly measure and specify hose length. As a result, a replacement hose may end up being either little shorter or little longer than the original part. When inches matter, the confusion about properly measuring hose length can result in delays and extra expense.

Brake Line Thread Identification: What it Entails

Thread identification means learning the thread size and pitch. The thread size is determined by the outside diameter of the male thread, or the inside diameter of the female thread. Pitch refers to the distance from one thread groove to the next (measured from crest to crest).

When replacing your brake lines, the replacement brake hose assembly does not need to look exactly the same as the original brake line, but make sure that the brake lines (especially the new brake hose fittings) will fit the surrounding area where they will be installed. Sometimes the brake hose fitting can interfere with another part of your brakes. Pay attention to any tight spots when removing your brake lines and communicate any restrictions to the vendor who will be fabricating your replacement brake lines.

Wire Braid Reinforcement vs. Wire Spiral Reinforcement

1. What’s the difference?
2. Why should you care?

Each style of hydraulic-hose wire-reinforcement has its advantages:

Parker has announced a running change to the crimp diameter and crimp length of HY series fittings. The change will be cosmetic for Parker’s rubber hoses produced by Parker Hose Product Division. There will, however, be some dimensional changes for the following thermoplastic hoses produced by Parker Parflex division: HFS2, HFS, D6, H6, R6, 563 and 53DM hoses in sizes 3/8” and 1/2”.

7 Most Common Crimping Mistakes

Parker Crimp die selection

Selecting the correct Parker crimp die to use with your Parker Crimper is essential to making a quality hose assembly. Sometimes it's tough to remember which Parker crimp die to use with each fitting.  The example below will show you a few easy steps to ensure every Parker hose assembly is crimped with the correct Parker crimp die.
