Flare Fittings – Technical Information
TubeFit Industrial Products provide a wide range of hose & fitting solutions to suit all industries.
SAE 45º Flare Fittings
Style and Description
Used extensively in the Plumbing and Gas Sectors, SAE 45º Flare fittings offer an excellent alternative to fittings that require a heat/flame to complete a seal. Flare fittings require the tube to be ‘belled’ or flared prior to assembly as the flared piece of tube is held in place between the nut and body.
Flare Fittings are ideal in situations involving mid-high level vibration.
Working Pressure
- 0-17250kPa depending upon tube size and media.
Media / Application
✓ Non-drinking water
✓ Gas
✓ LPG (Auto, domestic and commercial)
✓ Fuel and brake lines
✓ Refrigeration lines
✓ Hydraulics
✓ Pneumatics
Construction
- Flare Nut
- Flare Body
- Material: Brass
- Pipe Thread BSP: Tapered Male (R series) Parallel Female (Rp Series)
- Pipe Thread NPT
Tube
✓ Copper – Annealed and hard drawn
✓ Brass
✓ Aluminium
✓ Steel bundy
✘ Stainless Steel
✘ Nylon
✘ Poly tube
Assembly & Installation
- Cut the tube square, clean and remove any burrs or loose cuttings.
- Slide tube nut over the tubing.
- Using a 45º flaring tool, flare the end of the tube (as per tool instructions).
- After the tube has been flared, ensure the tube nut is able to pass over the flared end and mate with the seat of the nut.
- Assemble the tube nut onto fitting and tighten until ‘spanner firm’ (Caution: do not overtighten).
- If used in a pneumatic application, apply a soapy solution to the joint to be certain a positive seal has been made. Visually inspect for leaks if used in an hydraulic application.
SAE 45º Inverted Flare Fittings
Style and Description
As with other variations of flared fittings, Inverted Flare fittings require preparation of the tube prior to assembly.
Because of its compact design, suitability for applications involving high levels of vibration and excellent performance under high pressure, Inverted Flare can be found extensively in the Automotive Industry.
