Speciality Hose Types
Mixed Fitting Hoses (1/4" x 3/8")
Charging hoses with different fitting sizes on each end. Common configurations include:
- 1/4" SAE x 3/8" SAE — Connect standard manifolds to 3/8" equipment ports
- Red, blue, yellow options — Colour-coded for high/low/centre port identification
- Standard lengths — Typically 150cm (60") for general service work
Applications: Connecting standard 1/4" manifold gauges to equipment with 3/8" service ports, adapting between different fitting sizes without separate adapters, custom service setups requiring mixed fittings.
No-Core-Depressor Hoses
Specialist hoses without the core depressor pin in the fitting. These allow:
- Connection without opening valve cores — For ports with external valve cores
- Specific equipment compatibility — Some equipment requires non-depressing fittings
- Diagnostic applications — Pressure testing without affecting valve cores
Applications: Equipment with external Schrader valves, pressure testing applications, specific manufacturer requirements, and diagnostic work where valve cores must remain closed.
90° Shut-Off Valve Hoses
Flexible hoses with integrated 90° angled shut-off valves. Features include:
- Right-angle design — Perfect for tight spaces and awkward access points
- Integrated ball valve — Control flow without disconnecting hose
- Flexible hose section — Routes easily around obstacles
- Red and blue options — High and low-pressure configurations
Applications: Tight engine bays and confined spaces, awkward service port angles, mobile service work in challenging environments, and applications requiring flow control in restricted access areas.
1/4" Flare Hoses
Hoses with 1/4" flare fittings instead of standard SAE fittings:
- Low-pressure applications — Typically for low-side connections
- Specific equipment compatibility — Some equipment uses flare fittings
- Custom installations — Permanent or semi-permanent setups
When to Choose Specialty Hoses
- Non-standard equipment — Equipment with unusual fitting sizes or types
- Tight access situations — 90° valves for confined spaces
- Mixed fitting requirements — Connecting different fitting sizes without adapters
- Specific valve configurations — No-core-depressor for external valve cores
- Custom service setups — Unique configurations for specific applications
- Problem-solving — When standard hoses won't work for your application
Benefits of Speciality Hoses
- Solve unique challenges — Address service scenarios standard hoses can't handle
- Eliminate adapters — Mixed fittings reduce connection points and leak risk
- Improve access — 90° configurations reach difficult service ports
- Professional solutions — Purpose-built tools for specific applications
- Reduce service time — The Right tool for the job means faster, more efficient work

Mobile Service Work
- Challenging access situations in the field
- Variety of equipment types requiring different fittings
- Problem-solving tools for unexpected service scenarios
Professional Tips
- Identify requirements first: Confirm exact fitting types and sizes needed before ordering.
- Keep variety in stock: Mobile technicians benefit from having specialty hoses available
- Check compatibility: Verify speciality hoses work with your specific equipment
- Document applications: Note which speciality hoses work for which equipment
- Quality matters: Specialty applications demand reliable, professional-grade hoses
Choosing the Right Speciality Hose
- Identify the challenge: What specific problem are you trying to solve?
- Measure fittings: Confirm exact fitting sizes and types required
- Consider access: Will 90° valves help with tight spaces?
- Check valve cores: Do you need no-core-depressor fittings?
- Verify compatibility: Ensure the speciality hose works with your equipment
