Global Hydraulic Fittings Manufacturer | Factory-Direct DIN, SAE & BSP Connectors
As a premier manufacturer based in Ningbo's industrial hardware cluster, Fitsch delivers precision-engineered, leak-free hydraulic fittings built for high-pressure fluid and gas networks. Designed to join flexible hose assemblies, rigid steel tubing, and structural manifolds, our connectors serve as direct, high-performance replacements for global brands like Parker, Eaton, and Gates.
Forged from heavy-duty zinc-plated carbon steel, 316L stainless steel, and brass, Fitsch fittings withstand pressure surges, systemic vibration, and extreme temperature fluctuations across global mining, agriculture, construction, and industrial automation sectors.
High-Pressure Rigid Tube Couplings for DIN 2353,SAE J514, SAE J1453& ISO 8434-1,-2,-3 Systems
Fitsch mass-produces high-precision hydraulic tube fittings engineered to secure rigid metallic pipelines in heavy-duty, high-vibration equipment. Built strictly to international DIN 2353/ISO 8434-1, JIC 37-degree flare specifications SAE J514/ISO 8434-2, and ORFS SAE J1453/ISO 8434-3, our lineup guarantees tight micro-tolerances and complete interchangeability.
Product Types: Bite-type cutting ring fittings, JIC 37 degree flare fittings, and O-Ring Face Seal (ORFS) fittings.
Material Options: Heavy-duty carbon steel (Cr6-free zinc plated), 304/316L stainless steel, and brass.
Applications: Industrial automation networks, heavy machinery, and stationary hydraulic power units.
Key Advantage: Exceptional mechanical grip and dual-seal options that eliminate fluid creep under continuous thermal cycling.
