Preventing Rust on Hose Adapters

Have you ever tried to disassemble a hose from a piece of equipment, only to find that the rusted adapter won’t allow you to break the connection? Then you know about rust and the problems that can come with it! And it isn’t just connection problems…you can have system contamination, leaks, migrating rust to other components, maintenance issues, and it just looks terrible. Who wants rust on that beautiful piece of hydraulic equipment?

The Extensive Cost of Corrosion

Tube fittings aren’t typically replaced at the first sign of corrosion, however the cost of ownership begins to increase at this point because adjacent components begin to corrode at an accelerated rate. Consequently, corrosion resistance on fittings and adapters can be considered either a long-term investment or short-term price decision.

Corrosion can migrate to hydraulic hoses and even to costly hydraulic components. The cost implications of fitting corrosion with mobile equipment or industrial user can loom large if left ignored. Consider this Scenario:

Shop "A" Scenario
Adapters replaced due to corrosion failure (unable to be reused)


Shop maintenance hourly rate


Average time to replace adapter

150 fittings x $40/hr. x .25 hrs. =

15 mins. = .25 hrs.

$1500 annually

Hose assemblies requiring replacement due to adjacent corrosion failure


Price per hose assembly


Average replacement time for hose assembly

6 hoses at $90 each + $40/hr. x .25 hrs. x 6 hoses =

15 mins. = .25 hrs.

$600 annually

Hydraulic components requiring replacement due to adjacent corrosion failure


- Cylinder replacement


- Remove and replace cylinder

$700 + $40/hr x 1 hr.

1 hr.

$740 annually

* Additional hidden costs such as make-up oil shop supplies, transportation and freight/pickup of components are not included.

The cost of corrosion accounted for $276 Billion per year. Yes, B as in Billion! Do you fit in one of these categories?

Red Rust Deterioration of Fittings can cause:

  • system contamination
  • potential leaks
  • fitting connection problems
  • aesthetic quality concerns from end-user
  • maintenance difficulty
  • improper function of adjacent components (valves, pumps, cylinders)
  • accelerated corrosion of adjacent components

Parker Tube Fittings with Superior Plating

Preventing Rust on Hose Adapters 3

Prevent the ravages of red rust longer – tube fittings with Parker Superior Plating have unrivaled corrosion and rust protection. See for yourself in the salt spray photo above. Learn more about salt spray testing. At 480 hours with no red rust formation, the Parker fittings far exceed the 96 hour SAE requirement and resist red rust formation many times longer than the competition.

Parker’s Tube Fitting Division has rolled out a new plating called ToughShield (TS1000) that protects their adapters from rust, even in many severe applications like marine, mining and mobile environments, for up to 1,000 hours. The SAE requirement is only 72 hours, so this is a huge improvement. And this new plating offers protection at no additional cost. Nothing else is changing – the adapters have the same torque values, coefficient of friction, pressure ratings, color, and other specifications. Learn more about ToughShield.

Stop by one of our Cross Hose & Fitting stores to talk to a specialist and see how you can prevent red rust in your application. We stock a wide selection of sizes and thread styles of Parker adapters protected with durable, high-quality TS1000 plating, to help you reduce replacement costs and downtime. If you want to extend the life of your fittings further, ask our associates about stainless steel fittings.
