Product Description

PRODUCT INTRODUCTION

Carbon Steel Hydraulic Adapters

Strength, Reliability, and Versatility You Can Trust
Our carbon steel adapters are designed to connect pipes, hoses, and hydraulic components with different thread formats. We offer a wide selection of thread types, including:
Metric (DIN 2353, ISO 6149)
BSPP / BSPT (British Standard Pipe)
NPT / NPTF (National Pipe Tapered)
JIC (SAE 37° Flare)
ORFS (O-Ring Face Seal)
UNF, SAE Straight Thread
Configurations include male-male, male-female, bulkhead, tee, elbow, cross, straight, and custom types. These adapters are suitable for use in hydraulic, pneumatic, fuel, water, and lubricant systems.
 
Material Excellence: Why Our Carbon Steel Is Superior
We use precision-machined 45# high-grade carbon steel for all our hydraulic adapters. Compared to generic castings or low-grade steel from other manufacturers, our material offers:
Superior tensile and yield strength – for resistance to deformation under high loads.
Excellent machinability – for tight tolerance threads and smooth sealing surfaces.
Reliable toughness and fatigue resistance – for performance in high-vibration and shock-prone environments.
After machining, all adapters undergo zinc-nickel electroplating or trivalent chrome plating to provide exceptional corrosion resistance, far exceeding standard zinc-coated products.
 
Key Product Features
High-Precision Threads: All threads are cut to international standards with CNC lathes for accurate, leak-proof installation. Tapered and straight threads meet ISO, SAE, and ANSI specs.
Leak-Free Sealing Surfaces: Flare, cone, and o-ring surfaces are machined to micron-level smoothness for optimal sealing and pressure retention.
High Working Pressure: Rated for up to 6000 psi (400 bar) depending on size and configuration.
Corrosion-Resistant Coating: Zinc-nickel plating passes ASTM B117 720+ hour salt spray testing, outperforming most standard zinc or phosphate coatings.
Custom Marking and Traceability: Every adapter is batch-coded for full production traceability. OEM logos and part numbers available on request.
