Technical Specifications and Applications

EF179 - R14 1 Wire Braid

• Construction: Sintered PTFE tube core with single stainless steel braid (303/304 series).
• Temperature Range: Continuous -54°C to +260°C.
• Standards: SAE J517 - 100R14.
• Applications: Suitable for environments requiring excellent chemical resistance, temperature tolerance, low friction, and non-contamination.
• Pressure Ratings: Working pressure ranges from 870 to 3260 psi depending on hose size; burst pressure up to 13040 psi.
• Bend Radius: Minimum bend radius varies from 40 mm (1.6 inch) to 300 mm (12 inch) depending on size.

EF381 - R14 2 Wire Braid

• Construction: Sintered PTFE tube core with double stainless steel braid (303/304 series).
• Temperature Range: Continuous -54°C to +260°C.
• Standards: Exceeds SAE J517 - 100R14 pressure requirements.
• Applications: Similar to EF179 but with higher pressure ratings due to double braid reinforcement.
• Pressure Ratings: Working pressure ranges from 1080 to 4490 psi; burst pressure up to 17960 psi.
• Bend Radius: Minimum bend radius from 50 mm (2 inch) to 420 mm (16.8 inch).

EF370 - Convoluted PTFE Hose

• Construction: Helically convoluted sintered PTFE tube core with single stainless steel braid (304/316 series).
• Temperature Range: Continuous -54°C to +260°C.
• Applications: Used where flexibility is critical, including automotive, chemical, pharmaceutical, food processing, and plastic/rubber molding industries.
• Pressure Ratings: Working pressure from 500 to 1650 psi; burst pressure up to 6600 psi.
• Bend Radius: Minimum bend radius from 25.6 mm (1 inch) to 150 mm (6 inch).

EF371 - Convoluted Tape Wrapped PTFE Hose

• Construction: Helically convoluted sintered PTFE tube core with tape wrapping and single stainless steel braid (304/316 series).
• Temperature Range: Continuous -54°C to +260°C.
• Applications: Similar to EF370 with enhanced protection due to tape wrapping; suitable for dissipating electrostatic charges in some cases.
• Pressure Ratings: Working pressure from 500 to 1650 psi; burst pressure up to 6600 psi.
• Bend Radius: Minimum bend radius from 25.6 mm (1 inch) to 150 mm (6 inch).

EF382 - Gas Hose

• Construction: PTFE core with blue color pin-pricked polyurethane reinforcement; other colors available on request.
• Temperature Range: -40°C to +100°C (max +70°C for air and water-based fluids).
• Applications: Designed for airless paint spray systems operating at 200 to 325 bar, chemical resistance to solvents and aggressive fluids, moisture cure adhesives, and two-component chemical transfer.
• Pressure Ratings: Working pressure from 2170 to 5300 psi; burst pressure up to 15900 psi.
• Bend Radius: Minimum bend radius from 40 mm (1.6 inch) to 320 mm (12.8 inch).

EF341 - Paint Spray PTFE Hose

• Construction: PTFE core with unspecified reinforcement.
• Temperature Range: Not explicitly stated but implied similar to other PTFE hoses.
• Applications: Airless paint spray systems requiring chemical resistance and high pressure handling.
• Pressure Ratings: Working pressure from 2900 to 4700 psi; burst pressure up to 18800 psi.
• Bend Radius: Minimum bend radius from 70 mm (2.8 inch) to 120 mm (4.8 inch).

General Product Characteristics

• Excellent chemical resistance and temperature tolerance (-54°C to +260°C for most PTFE hoses).
• Low coefficient of friction and resistance to deterioration.
• Non-contaminating properties suitable for pharmaceutical and food processing applications.
• Some hoses can be made conductive to dissipate electrostatic charges.
• Construction typically involves sintered PTFE tube cores reinforced with stainless steel wire braids (single or double).
• Custom manufacturing and private branding available with low minimum order quantities.
