Welcome to Fitsch, your premier one-stop segmented supplier and manufacturer of high-performance fluid power solutions. Our premium DIN 7241-B Hydraulic Quick Couplings (universally interchanged as ISO 7241-B or ISO-B series) are meticulously engineered to satisfy the most grueling quality control standards in industrial fluid transfer.
Leveraging our advanced factory network equipped with over 200 high-precision CNC machines, Fitsch delivers robust double shut-off quick disconnect systems that eliminate line leakage and shield against hydraulic contamination. Each coupling features heavy-duty self-sealing poppet valves that engage automatically upon disconnection, alongside a precise radial ball-locking sleeve assembly built to absorb heavy system vibrations.

Premium Segmented Materials for Any Environment
Through our highly efficient segmented supply chain management, we drastically lower procurement costs without sacrificing raw integrity. Our DIN 7241-B couplers are bulk-manufactured in three specialized material lines:
Hardened Carbon Steel: Protected with ZN-Fe (CRIII) plating for supreme durability in general machinery and heavy mobile hydraulics.
316 Stainless Steel: The premier selection for chemical process plants, aerospace sub-assemblies, and highly corrosive washdown environments.
Industrial Brass: Non-sparking and rust-resistant, tailored perfectly for marine, offshore platforms, and low-pressure fluid volume systems.
Whether your operations demand standard high-pressure performance up to 3,600+ PSI or completely customized OEM thread geometries (NPT, BSP, or SAE), Fitsch’s massive monthly capacity of 1,500,000 units stands ready to scale alongside your business.

Technical Breakdown for Fitsch’s Product Detail Pages
1/4" Body Size (-04 / DN06): Engineered for tight spaces and high-pressure micro-fluidics. Commonly found in precision testing equipment, compact hydraulic tools, and laboratory instrumentation.
3/8" Body Size (-06 / DN10): The industry standard for medium-flow auxiliary applications. Frequently deployed on compact construction attachments, industrial power packs, and hand-held hydraulic tools.
1/2" Body Size (-08 / DN12): The most widely stocked and queried size globally. This is the baseline standard for agricultural tractors, implement attachments, and heavy mobile machinery lines.
3/4" & 1" Body Sizes (-12, -16 / DN20, DN25): Tailored strictly for high-volume fluid transfer. Best for large industrial factory lines, oil and gas extraction plants, and heavy-duty dump truck systems.
