Buy & Import Elbow O Ring Boss/37DEG 56519-12-8-S from Amlpp Petroleum Parts - Wholesale Supply

The Elbow O Ring Boss/37DEG 56519-12-8-S is a precision hydraulic fitting designed for high-pressure fluid systems, featuring a 37-degree flare connection compliant with JIC standards and an O-ring boss threaded port for leak-free sealing. It is manufactured from stainless steel 316, offering superior corrosion resistance in aggressive environments such as diesel fuel lines and hydraulic presses. The fitting’s dimensions are standardized to 12-8-S thread size, with a 37-degree flare angle ensuring compatibility with standard hydraulic tubing.

This component is typically used in mobile and industrial hydraulic systems where vibration resistance and seal integrity are critical. The stainless steel 316 material is standard for applications exposed to saltwater, chemicals, or high-temperature fluids, and the O-ring boss design eliminates the need for additional sealing washers. Unlike carbon steel equivalents, this fitting resists pitting and crevice corrosion, extending service life in marine, offshore, and heavy equipment contexts.

Buyers commonly source this fitting for OEM maintenance, repair, and retrofitting of diesel engine fuel systems, drilling rig top drives, and mobile hydraulic units. The product is supplied in bulk, with packaging typically in polyethylene bags or cartons, though exact packaging may vary by order volume. Lead time and minimum order quantities are not specified in the listing and should be confirmed directly with the supplier. Trade terms such as Incoterms and payment methods are not listed and require direct negotiation.

Frequently Asked Questions About Elbow O Ring Boss/37DEG 56519-12-8-S from Amlpp Petroleum Parts
The thread is 12-8-S, a standard SAE J514 male O-ring boss thread designed to seal against a female O-ring boss fitting. This ensures a metal-to-rubber seal without additional gaskets. Buyers should verify thread pitch and diameter using a thread gauge to ensure compatibility with existing hydraulic lines.

Sourcing Elbow O Ring Boss/37DEG 56519-12-8-S from Amlpp Petroleum Parts - China Import Guide

Before placing an order, verify the exact thread dimensions using a calibrated thread gauge and confirm the flare angle with a 37-degree template. Request material certification for SS316, including chemical composition and mechanical properties, even if not provided. Ensure the fitting matches the existing system’s tubing size and pressure rating. Do not assume compatibility based on part number alone; cross-reference with OEM specifications.

Lead time and Incoterms are not stated in the listing and must be confirmed directly with the supplier. Typical trade terms for Chinese hydraulic fittings are FOB Shanghai or CIF destination port, with payment via T/T 30% advance and 70% against shipping documents. Packaging is usually in polybags inside cartons, but bulk orders may require palletization. Confirm minimum order quantity and whether samples are available before bulk purchase.

For quality assurance, request a sample batch for dimensional inspection and pressure testing. Check for surface imperfections, consistent flare geometry, and proper O-ring groove depth. Verify that the material is truly SS316 by requesting a material test report (MTR) with spectrometer data. Ensure all documentation, including packing lists and certificates, is provided in English and matches the order. Retain a sample for future reference if used in critical systems.
