1 PA6 vs PA66 Standard Performance and Economy
- This line serves as a high-strength hard nylon tubing option for standard industrial installations.
- Fluid Compatibility Air water oil fat
- Temperature Range Air -40C to +125C | Water 0C to +70C
- Max Pressure 2.0 MPa
- Applications Plant automation machine parts cooling lines
- Selection and Cost Choose this if your system runs under normal temperatures transfers basic compressed air and requires rigid lines like a standard black nylon tube. This is the most economical grade offering the lowest procurement cost for a reliable nylon air line tubing layout.
- Fluid Compatibility Air water oil fat solvents
- Temperature Range Air -40C to +135C | Water 0C to +70C
- Max Pressure 2.0 MPa
- Applications Automotive components electrical insulation high-heat fluid transfer
- Selection and Cost Upgrade to PA66 if standard pa 6 tubing fails due to ambient temperatures exceeding 125C or exposure to industrial solvents. Raw material cost is slightly higher than PA6 but remains highly cost-efficient for high-heat environments.
2 PA11 Premium Flexibility and Long-Term Durability
- This grade functions perfectly as a nylon flexible hose for systems requiring reliable structural bending.
- Fluid Compatibility Air water oil general-purpose corrosive media
- Temperature Range Air -40C to +100C | Water 0C to +70C
- Max Pressure 1.3 MPa
- Applications Aerospace fuel pipes medical equipment lubrication systems
- Selection and Cost Select this if your application involves constant dynamic vibration outdoor UV exposure or specifically mandates bio-based materials. It works exceptionally well as a heavy-duty nylon brake line. Raw materials are more expensive due to bio-sourced production castor oil.
3 PA12 and Soft PA12 Low-Temperature and Chemical Resistance
- The ideal series when you need pa12 tubing or transparent options like clear nylon tubing for clear fluid monitoring.
- Fluid Compatibility Air water oil general-purpose acids and bases
- Temperature Range Air -40C to +100C | Water 0C to +70C
- Applications Automotive layouts electronics chemical fluid transfer packaging machinery
- Selection and Cost Choose pa12 hose if the system is exposed to chemical acids bases or operates in extreme sub-zero climates down to -40C where regular nylon becomes brittle and cracks. It provides a robust nylon pressure tubing solution with the lowest water absorption rate.
Soft PA12 Langchi LCTS
- An ultra-flexible variant designed to fit exact imperial layouts such as 1 4 nylon tubing configurations.
- Fluid Compatibility Air water oil general-purpose acids and bases
- Applications Narrow workspaces robotic arms compact automotive routings
- Selection and Cost Select this soft version if you need the exact chemical and sub-zero performance of PA12 but your layout has tight enclosures or moving joints that require a small bending radius without kinking.
Summary Selection Checklist
LCPA PA6 Most economical choice. Features high rigidity and reliable mechanical strength for standard industrial fluid lines under normal temperatures.
LCPB PA66 Low-to-mid pricing. Matches standard rigidity but expands the temperature threshold up to +135C for superior high-heat reliability.
LCPC PA11 Premium pricing. Lower hardness 60D ensures excellent flexible movement outstanding outdoor weather resistance and compliance with green bio-based standards.
LCT PA12 Mid-to-high pricing. Delivers exceptional chemical stability against general-purpose acids bases and maintains robust low-temperature performance down to -40C with minimal water absorption. Perfect as a high-durability nylon air tubing alternative.
LCTS Soft PA12 Mid-to-high pricing. Engineered with the lowest hardness 58D and tightest bending radius. Retains all premium traits for dense tight machinery and dynamic automated joints.
