00018 is the standard ferrule for SAE 100R7 thermoplastic hydraulic hose. It provides a strong crimp grip between the hose cover and the fitting body. This guide from Hand Hydraulic covers sizes, dimensions, compatible hose, and correct crimping practice.
A 00018 ferrule is a cylindrical steel sleeve used in crimped hose assemblies. It slides over the end of a thermoplastic hose before the fitting is inserted. During crimping, the ferrule is compressed inward so it locks the hose reinforcements against the fitting stem.
These ferrules are sized for SAE 100R7 non-conductive thermoplastic hose. The 00018 profile gives a clean, concentric crimp that resists pull-off under pressure. Standard production is carbon steel with zinc plating; other materials and finishes are available on request.
Designed for R7 hose: The 00018 profile matches the outer diameter and reinforcement structure of SAE 100R7 thermoplastic hose.
Carbon steel construction: Drawn or machined carbon steel provides consistent wall thickness and crimp uniformity.
Corrosion-resistant finish: Zinc or yellow zinc plating protects the ferrule in wet, oily, or outdoor conditions.
Clean bore: Smooth inner surface helps the ferrule slide onto the hose without cutting the cover.
100% inspection: Each batch is checked for dimensions and surface quality before shipment.
The table below lists the standard 00018 part numbers and their reference dimensions. Confirm the actual hose outer diameter before ordering because manufacturer tolerances can vary.
See the 00018 ferrule product page for stock sizes, pricing, and customization options.
00018 ferrules are built for SAE 100R7 thermoplastic hydraulic hose. R7 hose has a thermoplastic inner tube, textile or synthetic reinforcement, and a thermoplastic cover. It is lighter and more flexible than rubber braid hose in many applications.
Working pressure depends on the hose grade and size, not the ferrule alone. Always pair the ferrule with fittings designed for the same hose series. Reusing a ferrule from a different hose family can create a weak joint or cause leakage.
Measure the hose outer diameter with calipers.
Choose the ferrule dash size that matches the hose bore and OD.
Select a fitting designed for SAE 100R7 hose in the same dash size.
Slide the ferrule onto the hose, insert the fitting stem, and position the assembly in the crimping machine.
Set the crimp die and final crimp diameter according to the fitting manufacturer’s specification.
Inspect the crimp for concentricity, correct length, and no visible cracks.
If you are unsure about the right crimp spec, contact us with your hose details and we will recommend the correct ferrule and fitting combination.
SAE 100R7 hose assemblies with 00018 ferrules appear in systems that need medium-pressure, flexible routing. Common applications include:
Forklifts and aerial work platforms
Injection molding machines
Machine tool hydraulics
Agricultural and lawn equipment
General industrial fluid power systems

A 00018 ferrule is a crimp sleeve designed for SAE 100R7 thermoplastic hydraulic hose. It compresses around the hose outer cover to create a permanent, leak-resistant assembly with a compatible hose fitting.
Standard 00018 ferrules fit hose dash sizes from -04 to -12, matching nominal hose bores from 6 mm to 20 mm. Always confirm the actual hose outer diameter before selecting the ferrule.
The standard 00018 ferrule is produced from carbon steel with zinc or yellow zinc plating for corrosion resistance. Stainless steel and other finishes are available on request.
Yes, we can customize 00018 ferrules with special lengths, surface treatments, and OEM markings according to customer drawings or samples.
Match the ferrule and fitting to the hose outer diameter, set the crimping machine to the manufacturer’s crimp specification, and inspect the finished crimp for correct final dimension and concentricity.
