What Are Stainless Steel One Piece Hose Fittings?
Stainless steel one piece hose fittings are integrated crimp fittings designed for high-pressure hydraulic hose assemblies. Unlike traditional two-piece designs, the stem and ferrule are manufactured as a single unit, ensuring precise alignment, consistent crimp performance, and reduced assembly error.
The one-piece construction improves structural strength and simplifies hose production, making these fittings ideal for bulk crimping operations and OEM hydraulic systems. Manufactured from corrosion-resistant stainless steel, they provide secure hose retention and reliable sealing in demanding industrial environments.
Our stainless steel one piece crimp hose fittings are dimensionally interchangeable with Parker® one-piece series and other major international hydraulic brands, allowing seamless replacement and compatibility in existing systems.

Which hose types are compatible with your one piece series?
Our series supports various hose constructions, including:
- SAE 100R1 / R2
- SAE 100R7 / R8 (Thermoplastic)
- SAE 100R12
- SAE 100R13 / R15
- SAE 100R14 (PTFE)
Correct series selection depends on hose reinforcement type and pressure rating.
Are your fittings interchangeable with Parker® series?
Yes. Our stainless steel one piece crimp hose fittings are dimensionally interchangeable with Parker® one-piece series and compatible with major hydraulic crimping systems.
What pressure ratings do your fittings support?
