37 Degree Flared Tube Fittings - General Information

APPLICATION

Sealexcel 37 degree flared Tube Fittings is 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

Sealexcel 37 degree flared Tube Fittings consist of three precision components such as Body, Sleeve and Nut. These components have been manufactured to very stringent tolerances under rigid quality control procedure approved to ISO 9001 : 2000.

Sealexcel 37 degree flared Tube Fittings meets SAEJ514 Standard.

The Tube end is flared at a 37 degree angle and sandwiched between the fitting body nose (seat) and the sleeve with nut which provide a very effective leakproof joint, full flow connection in process tubing.

Sealexcel 37 degree flared Tube Fittings are available as a standard in SS316 material, which meets the following specifications.

A. SS316 Bar Stock	ASTM A-479
B. SS316 Forging	ASTM A-182

Other materials are available on request.

PRESSURE RATING

Sealexcel 37 degree flared Tube Fittings provide zero leak, 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.

Metric Size	ranges from 6mm through 25 mm

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.

AVAILABLE SIZES

Metric size ranges from:	4mm through 16mm Tube OD
Fractional size ranges from:	3/16" through 5/8" Tube OD.
Recommended tolerance on tube ±0.05 mm

ASSEMBLY INSTRUCTION

• Ensure that the end of the tube is cut square within ±1 degree 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 37 degree, dimensions of Flared Tube according to SAEJ533 standard as shown below
