Alternatives & configuration differences

These are distinct configurations, not an automatic interchange or fitment guarantee.

Part number	Configuration	Difference
177.13B178C	Automann 177.13B178C	177.12C748C explicitly has Composite body and Swivel pivoting; 177.13B178C explicitly has Brass body and Fixed pivoting. Both own sources list a Brass collet and the separately labelled 1/2-inch tube O.D. / 3/8-inch male NPT interfaces. Selection conditions This is a manufacturer-listed Alternative Items configuration relationship, not a guarantee of interchangeable installed fit. Both articles have their own exact saved source: 45-degree male elbow, push-lock connect, tube-to-male-NPT, 1/2-inch tube O.D., 3/8-inch male NPT and nylon tube used-with. Tube O.D. and nominal pipe thread are distinct labels. Each own source explicitly states Brass collet. The body difference is Brass versus Composite; Composite is not expanded to a particular polymer. Fixed versus Swivel is each own Type of Pivoting value, not a claim of continuous rotation under pressure or permission to swivel after installation. The composite own title and alternative card contain DOT; the brass own title does not. No DOT certification, independent compliance, pressure/temperature/fluid rating or air-brake suitability is transferred or newly established by this comparison. Applications Universal is only captured wording, not universal vehicle fitment. Confirm the required body construction and fixed/swivel installation arrangement, nylon-tube and NPT interfaces, service ratings and applicable installation/compliance instructions before selecting. No performance, corrosion, torque, tube-release, sealant, dimensions beyond labelled interfaces, package inclusion or safety equivalence is inferred. Only these exact two published target identities are linked. Other Alternative Items and ItemGroups are retained as separate source contexts, not transitive crosses, same-fit guarantees or counterpart-property evidence. All original claims, conflicts and holds remain unchanged; independent and human review are still required.
