Stainless Steel NPT Pipe Hydraulic Adapters
QC Hydraulics Pipe fitting stainless steel adapters use a NPTF (National Pipe Tapered, Fuel / equivalent to NPT National Pipe Taper) thread to mate male NPT to female pipe thread (parallel NPSM and tapered NPT)
NPT stands for National Pipe Tapered threads, also known as ANSI/ASME B1. 20.1 pipe threads. It is a U.S. standard for measuring tapered threads on threaded pipes and fittings.
Stainless Steel O-Ring Boss SAE/ORB Hydraulic Adapters
QC Hydraulics ORB (O-ring Boss) fittings or SAE fittings are similar to a JIC fittings without the 37 degree flare. They also have an o-ring for additional sealing.
This fitting is also known as O-Ring Boss (ORB) Recommended by the NFPA for optimal leakage control in medium and high pressure hydraulic systems. The male fitting has a straight thread and O-ring. The female port has a straight thread, a machined surface (minimum spotface) and a chamfer to accept the O-ring.
Stainless Steel O-Ring Face Seal(ORFS) Hydraulic Adapters
QC Hydraulics O-ring face seal type fitting that consists of a nut, a body, an O-ring and a sleeve… When the fitting is assembled, it compresses an O-ring in the precision machined groove of the fitting body to form a leak tight seal.
O-ring Face Seal have an o-ring in the face of the fitting to help make a better seal.
Stainless Steel JIC 37 Degree Flare Adapters Hydraulic Adapters
QC Hydraulics JIC or AN Fittings Have a 37 degree flare to make a metal to metal seal. They are an extremely common thread in the hydraulic world.
JIC (or Joint Industry Council) fittings, defined by SAE J514, are compression fittings machined with a 37 degree flare seating surface and parallel threads. They are commonly manufactured in nickel alloys, brass, carbon & stainless steel.
JIC Fitting hydraulic connections are common in most fluid power systems. Both male and female components have 37 degree seats. The seal is made by establishing contact between the male flared and the female coned seat. This is considered a mechanical connection. There are three components that make a tubing assembly; fitting, flare nut and sleeve.

√8. Why Choose Us?
QC Hydraulics is an ISO 9001:2015 certified manufacturer with over 20 year's manufacturing experience, specializing in hydraulic hose fittings and adapters. We only focus stainless steel material, no carbon steel or brass.
√2. Quality Control Of Raw Material:
1. We only choose the highest quality stainless steel raw material. And metal suppliers provide material test certificates for each shipment.
2. We 100% measure the sizes of bar stock and forging blanks by callipers for each shipment.
3. We use the Portable XRF Analyser to test the key chemical elements of bar stock and forging blanks with 10% for each shipment(Key chemical elements include Cr, Ni, Mo, these chemical elements are very important for the corrosion performance)
4. Besides, we randomly pick up several of cutting pieces to do further chemical analysis by spectrograph every 10 days to make sure the raw material 100% qualified.
√3. Quality Control Of Production Process:
1. We are using Sigma High-Precision CNC Lathe Machines to manufacture stainless steel hose fittings and adapters.
The features of CNC Lathe Machines:
1). Dual-axis, Mitsubishi system
2). Thread cutting tools: Mitsubishi Japan, vargus & carmex Israel(Have a very stable performance during machining)
2. We use callipers to measure the basic sizes. And we use the thread gages to inspect the threads.
3. We use Contracer & Contour Measuring Machines to inspect the very small angles and diameters.
√4. Inspection:
1. First Article Inspection During Process
1).The operator make the first article according to manufacturing drawings.
2). The operator will inspect the first article and record. If the sizes and threads meet the manufacturing drawings, and then the first article will be put in a special box( the box is for first article only).
3). Workshop foreman will take second inspection for the first article.
4). Only passing the inspection by workshop foreman, and then start with mass production.
2. Mass Production After First Article Inspection
1).After the first article approved by operator and workshop foreman, and then start with mass production.
2). During mass production, the operator needs to inspect the threads every 10 pieces, and measure the sizes every 15 pieces. Once any fittings of threads and dimensions out of the specs, all this batch of fittings will be inspected completely.
3). The qualified fittings will be fitly put in a plastic box piece by piece.
4). Finally, the finished fittings will be transported to inspection department for final inspection.
3. Final Inspection
2). Key sizes and angles: 15-20% randomly inspection by callipers and contracer. Once any sizes and angles of fittings out of specs or doesn't respect to drawings, this batch of fittings will be forced to return back to production workshop to improve or make a new replacement.
