ISOBARIC PRESSURE PERFORMANCE
PSB’s HB Series represents the next generation of industrial-grade hydraulic hose engineering. Each hose is designed with a constant working pressure rating — from 3,000 PSI to 6,000 PSI — regardless of diameter. This uniform pressure profile simplifies system design, improves safety margins, and ensures predictable performance in high-demand hydraulic applications.
Manufactured using advanced braided reinforcement and precision rubber compounds, our Isobaric hoses deliver exceptional flexibility, abrasion resistance, and impulse durability. Whether your equipment runs excavators, skid steers, material handlers, injection systems, or industrial automation, the HB Series is built for uptime and reliability.
Every HB Series hose is available with custom crimped fittings, assemblies cut-to-length, and same-day service options for local customers. PSB ensures your equipment stays online — with hoses that meet or exceed SAE and ISO hydraulic performance standards.

Frequently Asked Questions
-
Isobaric hoses are engineered to maintain a constant working pressure across all sizes in the series. This simplifies system design, improves safety margins, and ensures predictable performance in high-demand hydraulic applications.
-
The HB Series includes constant-pressure hoses from 3,000 PSI to 6,000 PSI, depending on the model. HB3K and HB3KXT are 3,000 PSI, HB4K and HB4KXT are 4,000 PSI, and HB5K, HB5KXT, and HB6K range from 5,000 to 6,000 PSI.
-
HB Isobaric hoses are ideal for construction equipment, industrial machinery, injection systems, skid steers, loaders, material handlers, and high-cycle hydraulic systems that demand flexibility, high impulse durability, and consistent pressure performance.
-
XT models (HB3KXT, HB4KXT, HB5KXT) include an extra-tough abrasion-resistant cover and upgraded braided reinforcement for harsh environments, heavy-duty cycles, and applications requiring maximum durability.
-
Yes. PSB provides custom cut-to-length assemblies, precision crimping, fittings, adapters, and same-day service for local customers. Every HB Series hose is assembled to meet SAE and ISO hydraulic performance standards.
