We maintain a massive production inventory across our factory alliance, allowing us to mass-produce up to 1,500,000 fluid connectors per month across key connection profiles:
DIN Compression Fittings: Utilizing cutting rings or DKO soft-seal O-ring cones to provide high-pressure mechanical holds.
JIC Hydraulic Fittings: Employing industry-standard 37-degree flared configurations for reliable metal-to-metal sealing.
O-Ring Face Seal (ORFS) Fittings: Incorporating elastomeric flat-face O-ring sealing faces to absorb heavy vibrations.
SAE Flange Fittings: Built for heavy-duty operational stability using split or one-piece flange clamp sets.
To ensure global interchangeability and direct replacement capabilities for tier-one brands like Parker and Eaton, all Fitsch fluid connectors strictly comply with international engineering specifications.
DIN 2353 / ISO 8434-1 Metric Compression Fittings PDF Catalog Download
Engineered for metric tube outside diameters (O.D.) ranging from 4 mm to 42 mm. These 24-degree cone bite-type fittings are categorized into three distinct working pressure ratings:
LL (Extra Light-Duty): Rated up to 10 MPa (100 Bar) for low-pressure lines.
L (Light-Duty): Rated from 10 MPa to 25 MPa (100 to 250 Bar) for standard machinery.
S (Heavy-Duty): Rated from 25 MPa to 63 MPa (250 to 630 Bar) for ultra-high-pressure industrial systems.
Temperature Thresholds: Operating ranges span from −40°C to +120°C for zinc-nickel carbon steel, up to +175°C for brass, and up to +200°C for high-grade Stainless Steel Fittings.

Fitsch also supplies a complete range of high-pressure connectors adhering to global specifications:
SAE J514 / ISO 8434-2 JIC 37° Flare Fittings PDF Catalog Download
Metal-to-metal sealing solutions for mobile and agricultural machinery. Designed for mechanical tube flaring applications, accommodating tube O.D. dimensions from 6 mm to 50.8 mm (1/4" to 2"). These fittings deliver consistent performance across a working pressure range of 10.5 MPa to 35 MPa. They provide a secure, metal-to-metal connection ideal for North American agricultural, construction, and mobile material handling machinery.
SAE J1453 / ISO 8434-3 ORFS Fittings PDF Catalog Download
Elastomeric flat-face O-ring options designed for high-vibration applications.Engineered specifically for high-vibration environments, ORFS technology seals tightly against flat-faced tube ends spanning from 1/4" to 1-1/2" (6 mm to 38 mm). With a maximum working pressure ceiling of 25 MPa to 63 MPa, the built-in elastomeric O-ring traps fluid safely, making it a benchmark component for heavy construction machinery and recycling equipment.
SAE J518 / ISO 6162 Split Flange Clamps PDF Catalog Download
Code 61 and Code 62 configurations built for high-flow, heavy-duty industrial systems.Built for larger, high-flow conduits, these flange components secure 37-degree flared tubes or weld sleeves ranging from 13 mm to 127 mm.
Code 61 Series (ISO 6162-1): Covers medium-pressure boundaries from 3.5 MPa to 35 MPa (35 to 350 Bar).
Code 62 Series (ISO 6162-2): Handles heavy-duty applications demanding maximum structural limits up to 42 MPa (420 Bar).
For non-standard specifications, Fitsch utilizes advanced CNC machinery to deliver Custom Hydraulic Fittings tailored to precise client blueprints in carbon steel, stainless steel, brass, and aluminum.
Global Interoperability: Components cross-reference seamlessly with major international brands.
Rigorous Quality Control: Strict testing in compliance with ISO, DIN, SAE, BS, and JIS standards.
Reliable Logistics: Standard configurations ship with stable lead times to support global supply chains.
When standard off-the-shelf components cannot fulfill the parameters of your fluid handling system, Fitsch utilizes an advanced workshop array of over 200 high-precision CNC machines. We accept specialized blueprint projects and custom orders tailored to your exact industrial demands.
Whether your application calls for custom thread adapters, specialized block shapes, or high-volume material runs in carbon steel, stainless steel, brass, or aluminum, our engineering department provides technical guidance and rigorous QA verification to deliver compliant fluid connectors on schedule.
