Parker’s Hose Products Division has announced increased pressure ratings for select sizes of three E-Z FORM™ hose series: 7219, 7395, and 7399. The update applies to hose sizes up to 1 inch, and select sizes are now also approved for use with Parker 43 Series crimp fittings.
These changes give equipment builders, maintenance teams, and fleet operators more flexibility when specifying hose for compact routing, suction and return service, coolant systems, drain lines, and other industrial or mobile applications.
Western Integrated Technologies offers Parker hose products, hose assembly support, and hydraulic expertise to help customers select the right hose and fitting combination for the job.
What Changed?
Parker has increased the maximum working pressure for select E-Z FORM™ hose sizes up to 1 inch across the following series:
- Series 7219 — E-Z FORM™ MP Multipurpose Oil Resistant Hose
- Series 7395 — E-Z FORM™ GS General Service Hose
- Series 7399 — E-Z FORM™ HT High Temperature Hose
Across these series, the updated hose sizes now include working pressure ratings up to 150 psi. Select sizes are also approved for 43 Series crimp fittings. Please see the tables under each hose series heading below for compatibility with specific part numbers.
For currently qualified crimp specifications, including coupling designations, Parker directs users to CrimpSource.
Important: Couplings attached with bands or clamps may reduce the working pressure of the hose assembly below the hose’s maximum rated working pressure. Always follow applicable assembly guidelines and verify the complete hose assembly rating.
Series 7219 — E-Z FORM™ MP Multipurpose Oil-Resistant Hose
Parker Series 7219 E-Z FORM™ MP is designed for applications requiring a highly flexible, oil-resistant hose with suction and return capability. Its construction includes a black nitrile tube resistant to oil and refined fuels, multiple textile plies with a wire helix, and a black chloroprene cover with Parker’s Greek corrugated finish.
The wire helix provides full suction/vacuum capability and also creates a path to conduct static electrical charge to ground. The tightly pitched corrugations reduce bending force, improve kink resistance, and allow the hose to be routed through confined spaces where formed hose is often required.

Series 7219 should not be used in fuel dispensing or service applications requiring API, NFPA, UL, ULC, or other agency approvals or listings. Parker also advises users to refer to the refined fuel/hose compatibility information for media compatibility. Do not drag the hose across sharp edges or highly abrasive surfaces.
Series 7395 — E-Z FORM™ GS General Service Hose
Parker Series 7395 E-Z FORM™ GS is a general-service hose engineered for coolant, air, mild chemical, water, drain, and vacuum applications. It uses an EPDM tube that is resistant to commonly used coolant mixtures, multiple textile braids or plies with a wire helix, and a black EPDM Greek corrugated cover.
Like the other E-Z FORM™ hoses, Series 7395 is designed for applications where flexibility and compact routing are critical. The wire helix supports full suction/vacuum capability and provides a path to conduct static charge to ground.
Series 7395 Key Specifications
Specification Details Tube Peroxide-cured EPDM for sizes up through 1″; sulfur-cured EPDM for sizes above 1″ Reinforcement Multiple textile braids or plies with wire helix Cover Black EPDM; Greek corrugated finish Temperature range -50°F to +257°F (-45°C to +125°C) Design factor 4:1 Vacuum rating 29″ Hg (737 mm Hg) Industry standards SAE J20R2-D1 performance; UL94 Flame Resistance Rating HB Brand method Black text on blue stripe Series 7395 Applications
Series 7395 is commonly used for:

Series 7395 is suitable for coolant and general service environments where flexibility, vacuum capability, and resistance to abrasion, mild chemicals, heat, and ozone are required. Do not drag the hose across sharp edges or highly abrasive surfaces.
Series 7399 — E-Z FORM™ HT High Temperature Hose
Parker Series 7399 E-Z FORM™ HT is designed for high-temperature applications involving oil suction and return service. It features a black CPE tube, multiple textile braids with wire helix, and a black hydrogenated nitrile cover with Parker’s Greek corrugated finish.
Series 7399 is built for demanding environments where heat, oil exposure, weathering, and tight routing are key considerations. The hose provides full suction/vacuum capability and the wire helix offers a path to conduct static electrical charge to ground.
Series 7399 Key Specifications
Specification Details Tube Black CPE Reinforcement Multiple textile braids with wire helix Cover Black hydrogenated nitrile; Greek corrugated finish Temperature range -40°F to +302°F (-40°C to +150°C) Design factor 4:1 Vacuum rating 29″ Hg (737 mm Hg) Industry standards None applicable Brand method Black text on yellow stripe Series 7399 Applications

Series 7399 is a strong choice when higher temperature performance is required. As with the other E-Z FORM™ series, avoid dragging the hose across sharp edges or highly abrasive surfaces.
Why This Matters for Hydraulic and Industrial Applications
The increased pressure ratings expand the usefulness of Parker’s E-Z FORM™ hose platform in compact, demanding environments. These hoses are designed to reduce the need for pre-formed hose by offering exceptional flexibility, low force-to-bend, and strong kink resistance.
For maintenance teams and OEMs, that can mean:
- Easier hose routing in tight spaces
- Reduced need for custom formed hose
- Strong suction and vacuum performance
- Improved assembly options with approved coupling combinations
- Broader application coverage for mobile, industrial, and fleet equipment
However, hose selection should always account for the full application: pressure, temperature, media compatibility, routing, bend radius, environmental exposure, coupling method, and applicable agency or industry requirements.
