SAE37°FLARE 3-PIECE TUBE ASSEMBLY

Product catalog summary
Overview: This document outlines the technical specifications and assembly instructions for stainless steel 3-piece tube assemblies designed for high-pressure applications. These assemblies use 37° tube fittings ranging from 1/8’’ to 2’’ and comply with SAE Standard J514.
Specifications: The tubing must be fully annealed, seamless, and drawn, suitable for bending and flaring according to ASTM-269 standards, using A.I.S.I. 316 or 304 stainless steel. The finished tubing should be straight, smooth, and free from burrs and defects, adhering to SAE J524 quality standards.
Tube Handling: Proper handling is crucial to prevent leaks and scratches. Tubes should not be dragged on the floor or out of racks.
Tube Cutting: Tubes can be cut using a tube cutter or hacksaw. The tube cutter should ensure square cuts without deep incisions, and ends must be deburred. Hacksaw cutting requires guide blocks for square ends and deburring.
Assembly Instructions: 1. Cut the tube to the required length. 2. Slide the nut and sleeve onto the tube. 3. Form a 37° flare using a special tool as per SAE STD. J533. 4. Screw the nut onto the body finger-tight, then tighten with a wrench 1/4 turn for a leakproof connection.
Flaring Dimensions: Table 1 provides dimensions for single flare diameters and deburring requirements for various tube sizes.
Pressure Ratings: Table 2 lists allowable working pressure ratings for different tube sizes, noting that many factors influence system performance.
Components: The document includes a list of connectors, sleeves, nuts, and adapters with their respective SAE codes and dimensions for both inch and metric tubes.
Important Notes: NPT tapered pipe threads meet ASME/ANSI B.I.20.1 requirements. Metric tubes can be used with a metric 37° sleeve. Dimensions are subject to change without notice.

ASSEMBLY INSTRUCTIONS Perform flaring according to SAE J533. See Fig. 2. See Table 1 below for dimensions. Figure 2 TABLE 1: FLARING A Single Flare Diameter Max To ensure satisfactory flare production, tube end deburring might be required prior to flaring. It is usually necessary to break the inside corner smoothly before single flaring. In addition, some non-ferrous tubing is normally required to eliminate the cutoff burr, which might otherwise create leakage paths across a substantial portion of the flare. Smoothly breaking the outside corner prior to single flaring, or both the outside and...
