What Are One Piece Hydraulic Hose Fittings?

One piece fittings are hydraulic hose fittings in which the body and the ferrule are formed from a single blank, instead of a separate stem and collar. During assembly, the hose end is prepared, the stem section is inserted into the bore, and the whole body is compressed by a crimping machine. Because there is no separate ferrule to align, the crimp zone stays concentric with the hose by design.

Why engineers specify one piece fittings:

• One part instead of two: fewer components to stock, handle, and match
• Concentric crimp by geometry: no stem-to-ferrule misalignment
• Fewer leak paths and a cleaner outer profile
• Built for high-pressure spiral hose and PTFE (Teflon) service
• Single-use integrity: every assembly starts with a fresh, certified part

Core value: choosing the right one-piece fitting is the first step to a hose assembly that will not leak and will not pull apart.

Três percursos do cliente:

• Para fabricantes OEM — standardize one part number per assembly, reduce inventory lines, and lock in repeatable crimp results. Start here.
• Para utilizadores finais e equipas de manutenção — match your existing hose assemblies by standard and dash size, then repair in-house with the correct tooling. Start here.
• Para distribuidores — consolidate the full one-piece range in one catalog, with mixed-size sample kits and private labeling. Start here.

Connection-Side Options

The connection end of each one-piece fitting is configured to your machine port. This range is available with the following connection types:

Send us your port thread and standard. We confirm the correct connection configuration before production.

Hose-Side: One-Piece Fitting Families

The table below lists the four one-piece hydraulic hose fittings families in this range. Length (L) is the primary hose-side dimension, held to ±0.5 mm; outer diameter tolerance is ±0.1 mm for stable crimp results.

Dash size equals the hose I.D. in 1/16-inch increments: 03 = 5 mm, 06 = 10 mm, 12 = 20 mm, 20 = 32 mm, 32 = 50 mm. Note the exceptions: 00TF0-03 fits a 4 mm PTFE bore, and 01400-24 fits the 38 mm (1-1/2 in) R12 bore. Always match the dash size to the hose I.D., then confirm the cover O.D. against the applicable standard.

Material e acabamento da superfície

Material choice is the second decision when selecting hydraulic hose fittings for corrosive or hygienic service.

Principais características

• One-piece design: stem and ferrule in a single part
• High pressure: up to 450 bar (6,527 psi) on 4SP assemblies; 4,000 psi constant on R12
• Corrosion resistant: ≥120 h salt spray, zinc-nickel and stainless options
• SAE / DIN / ISO compliant: EN 856, SAE J517, ISO 8434-1
• Single-use certified: fresh part for every assembly, batch traceability on packaging

Crimping Tools and Installation

One piece hydraulic hose fittings are crimped with standard hydraulic crimping machines and common die sets. We provide reference crimp data and die selection for your machine model with every order, so no special tooling is required.

Installation steps:

1. Corte a mangueira em ângulo reto com um cortador de mangueiras afiado.
2. Prepare a extremidade da mangueira de acordo com as instruções do fabricante da mangueira (faça um corte raso onde for necessário, por exemplo, 4SH e R12).
3. Insert the stem section fully into the hose bore until it seats.
4. Position the assembly in the correct die set.
5. Crimp to the target crimp diameter from your hose manufacturer’s crimp chart.
6. Verifique o diâmetro exterior da crimpagem com um paquímetro e registe o valor.

Two rules prevent failures: always use the target crimp diameter from the hose maker’s chart, and never re-crimp a used one-piece fitting. One-piece fittings are single-use components. We supply them as matched sets with the correct stems for certified assemblies.

Nomenclature: How to Read a Part Number

Every one-piece fitting follows the same rule across all one-piece hydraulic hose fittings in this range:

SERIES - DASH

Take 00400-12 as an example:

More examples: 01400-24 is the R12 large-bore family at DN 38; 00TF0-08 is the small-bore PTFE family at DN 12; 00710-32 is the large-bore PTFE family at DN 50. When ordering, always quote the full part number with the dash suffix.

We do not list competitor part numbers on this page. Send us your hose brand, construction, and dash size, and our engineers verify the exact match for you before you order.

Applications and Industries

One piece hydraulic hose fittings are specified across these industries:

• Mining and tunneling: 4SP and R12 assemblies for drill rigs, crushers, and conveyor systems
• Construction and mobile equipment: 4SP and R12 for excavators, loaders, and telehandlers
• Oil and gas: 4SP and R12 for high-pressure transfer and well-service lines
• Chemical and pharmaceutical: PTFE assemblies in stainless steel for aggressive media
• Food and beverage: PTFE assemblies for hygienic process lines
• Steam service: PTFE assemblies for hot and condensate media
• Marine and offshore: spiral series with zinc-nickel plating

Working pressure and temperature ranges:

Selection note: 4SP, 4SH, and R12 assemblies are for hydraulic power transmission. PTFE assemblies are for chemical, food, and steam service, not for heavy hydraulic power. We state this honestly so you select the right part the first time.

Ordering and Packaging

• Unit of measure: sold per piece (EA), packed in boxes per size
• MOQ: one box per size; mixed-size sample kits available
• Customization: connection type, stainless steel material, zinc-nickel plating, private labeling, special packaging
• Export packing: corrugated cartons with moisture barrier for sea freight
