TS490-HO-LD 4" Precision Dispensing Nozzle - 3/32" Orifice, 1/4" NPT Thread (LDPE)
High‑Accuracy Industrial Nozzle for Sealants, Epoxies, Silicones & High‑Viscosity Materials
The TS490-HO-LD is a 4‑inch high‑precision industrial dispensing nozzle designed for controlled, repeatable application of high‑viscosity materials. Manufactured from softer LDPE, this nozzle delivers high stability and bead accuracy as an alternative to the more rigid HDPE versions - making it ideal for demanding aerospace, automotive, electronics, and industrial manufacturing environments.
Featuring a 3/32" (2.38mm) fine orifice and a 1/4" NPT male thread, the TS490-HO-LD provides universal compatibility with Techcon, Semco PPG, Nordson EFD cartridges and selected dispensing valves. The tapered LDPE body supports cut‑to‑length customisation, allowing operators to fine‑tune bead size and flow characteristics for specialised applications.
For 310ml and 400ml sealant cartridges with external nozzle nipple threads, pair this nozzle with the AD931‑296 adapter to ensure a secure, leak‑free connection.
Key Features
- A 4.0" (101.6mm) extended length for improved reach in tight or complex assemblies
- A 3/32" (2.38mm) fine outlet ID for precise, uniform bead control
- A 1/4" NPT male thread compatible with Techcon, Semco PPG, Nordson EFD cartridges
- Rigid HDPE construction for enhanced stability and reduced nozzle flex
- Cut‑to‑length design for adjustable flow and bead size
- Industrial‑grade, silicone‑free materials
- Rated to 100 PSI, suitable for pneumatic dispensing systems
Why Choose the TS490-HO-LD?
The TS490-HO-LD is engineered for operators who require fine bead accuracy, extended reach, and consistent flow performance. Its rigid HDPE body maintains shape under pressure, ensuring smooth, controlled dispensing of sealants, adhesives, epoxies, gels, and other high‑viscosity materials.
This nozzle is ideal for:
- Precision bead placement
- Deep‑reach dispensing
- High‑pressure pneumatic systems
- Professional‑grade assembly work
- Environments where bead consistency is critical
Compatibility - Cartridges & Systems
- Techcon cartridges
- Semco PPG cartridges
- Nordson EFD cartridges
- Selected dispensing valves - With 1/4" NPT Outlet Thread
- 310ml & 400ml sealant cartridges (with AD931‑296 adapter)
Materials Suitable for dispensing:
- Sealants & silicones
- Epoxies & resins
- Pastes & gels
- Greases & lubricants
- Mastics & potting compounds
- Polyurethane adhesives
- High‑viscosity industrial fluids
Flow Performance - 3/32" Fine Orifice
The 3/32" orifice provides:
- Smooth, uniform bead formation
- Excellent flow control
- Reduced dripping and inconsistency
- Reduce back pressure
- Professional‑grade accuracy for detailed assembly work
Combined with the 4.0" extended length, operators can apply fine beads in:
- Tight spaces
- Deep cavities
- Complex assemblies
- Hard‑to‑reach industrial equipment
4.0" Extended Length - Optimised Reach
The TS490-HO-LD offers double the reach of standard 2" nozzles, enabling:
- Access to recessed joints
- Precise bead placement in confined areas
- Improved operator control during long‑reach applications
This extended geometry is widely used in:
- Aerospace assembly
- Automotive manufacturing
- Electronics production
- Medical device assemblies
- Industrial maintenance
- Specialist engineering environments
Custom Bent Configurations Available
For specialised applications requiring unique approach angles or custom dispensing geometry, the TS490-HO-LD is available in custom bent configurations.
These options support:
- Complex assembly access
- Non‑linear bead placement
- OEM‑specific dispensing requirements
- Minimum order quantities and lead times might apply.
Installation & Fitment Guide
Thread the nozzle onto any 1/4" NPT cartridge outlet until fully seated.
- For 310ml/400ml cartridges with external threads, install the AD931‑296 adapter first.
- Trim the nozzle tip gradually if a larger bead size is required.
- Test flow on scrap material before production use.
- For pneumatic systems, ensure pressure does not exceed 100 PSI.
