Component Specifications

Definition
A precision-engineered pneumatic fitting designed to establish a secure, leak-free connection between compressed air supply lines and air knife/blower nozzle assemblies. This component ensures optimal airflow delivery while maintaining system pressure integrity through standardized thread interfaces and sealing mechanisms.
Working Principle
Operates by providing a mechanical interface that connects compressed air supply lines to air knife/blower nozzle bodies using threaded connections with sealing elements (typically O-rings or gaskets) to prevent air leakage. The connection maintains laminar airflow transition from supply line to nozzle body while withstanding operational pressure fluctuations.
Materials
Typically manufactured from aluminum alloys (6061-T6, 7075), brass (C36000), or stainless steel (304, 316) with Buna-N or Viton O-rings for sealing. Surface treatments include anodizing (aluminum), chrome plating (brass), or passivation (stainless steel) for corrosion resistance.
Technical Parameters
  • Seal Type O-ring face seal or tapered thread seal
  • Thread Sizes 1/4", 3/8", 1/2", 3/4" NPT common
  • Flow Capacity 10-100 SCFM (depending on size)
  • Connection Type NPT, BSPP, or BSPT threads
  • Pressure Rating 150-200 PSI (10-14 bar)
  • Temperature Range -20°C to 120°C
Standards
ISO 1179, DIN 3852, ISO 6149, SAE J514

Frequently Asked Questions

What is the difference between NPT and BSPP thread types for air inlet connections?

NPT (National Pipe Taper) threads are tapered and seal through thread interference, while BSPP (British Standard Pipe Parallel) threads are parallel and require a separate sealing washer or O-ring. NPT is common in North America, BSPP in Europe and Asia.

How do I prevent air leaks at the inlet connection?

Ensure proper thread engagement (hand-tight plus 1.5-2 turns with wrench), use appropriate thread sealant (PTFE tape or liquid thread sealant for NPT), and replace worn O-rings regularly. For BSPP connections, ensure the sealing washer is undamaged and properly seated.

What maintenance is required for air inlet connections?

Regular inspection for leaks, checking thread condition, replacing O-rings annually or as needed, and cleaning threads before reassembly. Use thread gauges to verify thread integrity if disassembly is frequent.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
