370 Flare Fittings

370 Flare Fittings


APPLICATION

HYDRO-PNEUMAX 370 Flared Tube Fittings are compact and simple in design for assembly and assures maximum reliability and performance. It is especially suited for low and medium wall tubing with good vibration resistance in a broad selection of types and sizes. It is used in virtually every application that uses Fluid Power for motion control & Automation.


DESIGN

HYDRO-PNEUMAX 370 Flared Tube Fittings consist of three precision components such as Body, Sleeve & Nut. These components have been manufactured to every stringent tolerance under rigid quality control procedure approved to ISO 9001:2015.

HYDRO-PNEUMAX 370 Flared Tube Fittings meets SAE J514 Standard.

The Tube end is flared at a 370 angle and sandwiched between the Fitting Body Nose (Seat) and the Sleeve with Nut, which provide a very effective leak free joint, full flow connection I process Tubing.

HYDRO-PNEUMAX 370 Flared Tube Fittings are available as a standard iv SS316 material, which meets the following specifications.

A. SS316 BARSTOCK: ASTM A-479
B. SS316 FORGING: ASTM A-182

Other materials are available on request.
PRESSURE RATING
HYDRO-PNEUMAX 370 Flared Tube Fittings provide zero leakage, full flow connection in Hydraulic System operating at working pressure as specified below.

Allowable working pressure ratings are based on min. design factor 4:1 for dynamic and 3:1 for static application.

QUALITY OF TUBING
Stainless Steel 316 or 304 seamless tubing should be fully annealed, according to Standard ASTM-269 suitable for bending and flaring. Length of finished tubing shall be reasonable straight and have smooth ends and free from burrs, scales and any kind of defect and scratches.
ASSEMBLY INSTRUCTION
  • Ensure that the end of the tube is cut square within ±10 and remove the burrs and sharp edges.
  • Wipe the ID and the OD of the deburred Tube end properly.
  • Insert the Nut and Sleeve on to the Tube as shown below.
 
 
Flare the Tube with a special flaring tool to 370, dimensions of Flared Tube according to SAE J533 standard as shown below.
