How do you stop a hydraulic fitting from leaking?

Use a piece of cardboard or wood instead of your hand to track down the source of a leak.

  1. Avoid Fire When Repairing Hydraulic Fitting Leaks.
  2. Never Ignore a Hydraulic Leak.
  3. Verify the Fitting Is the Source of the Problem.
  4. Fittings Can Be Overtightened.

What are the different types of hydraulic fittings?

The three most common types of hose fittings are O- ring, mated angle and threaded. However, there are several more types of hydraulic hose fittings available.

How do you tighten hydraulic fittings?


  1. Tighten the nut by hand until it bottoms the seats.
  2. Using a marker, draw a line lengthwise on the nut and extend it onto the adapter.
  3. Using a wrench, rotate the nut to tighten. Turn the nut the amount shown on the chart.

Do tapered fittings need Teflon tape?

Make sure that PTFE is right for the job. It should be used only on male tapered pipe threads. Do not use it on straight threads such as those used on flared, coned or tube fitting ends.

Is permatex the same as Loctite?

Loctite and Permatex are brand names IIRC Permatex is like the civilian/non-commercial brand name of Loctite. Loctite supplies a lot of interesting chemicals and products, including a moly-dry film lube similar to the stuff used on AR mags.

Is it OK to use Teflon tape on hydraulic fittings?

You don’t need or should use any teflon tape or pipe dope on hydraulic fittings. Neither are designed for those kinds of pressures and using them could create a less then perfect mating between connection surfaces causing more harm than good.

What are the three basic types of threads?

Three are parallel (UN/UNF, BSPP, metric parallel) and three are tapered (NPT/NPTF, BSPT, metric tapered). Three are pipe threads (NPT/NPTF, BSPT, BSPP) and three are not (UN/UNF, metric parallel, metric tapered). Keep in mind that tapered does not necessarily mean it is pipe thread (for example, metric tapered).

Can hydraulic fittings be used for water?

Hydraulic hoses are the ideal choice for efficient water transportation which requires a long lasting and industrial strength piece of equipment.

How do I know what type of hydraulic fitting I have?

Four Steps to Thread Identification

  1. Step 1 – Determine if the thread is tapered or parallel. NPT/NPTF and BSPT are tapered threads while UN/UNF and BSPP are parallel.
  2. Step 2 – Determine the pitch.
  3. Step 3 – Determine the size.
  4. Step 4 – Designate the thread.

How do you fix a leaky hydraulic hose?

6 Steps for Fixing Hydraulic Hoses

  1. Identify the Correct Hose.
  2. Remove the Damaged Area.
  3. Use an Adapter to Complete Installation.
  4. Confirm the Correct Length.
  5. Ensure a Proper Seal.
  6. Circulate Fluid at Low Pressure to Check for Leaks.

Can you over tighten an fittings?

Remember, over tightening will result in possible damage to the fitting, resulting in possible leaks.

Can you over tighten NPT fittings?

Over – tightening the connection can easily split the female portion of a pipe thread connection; this is especially an issue when installing male pipe thread fittings into cast iron ports on valves, motors, and cylinders. Using a liquid thread sealant for NPT connections is recommended over using Teflon tape.
