Jensen Global JG22-1.25TT, 22 Gauge 1.25 in IT Series Tapered Dispensing Tip, 1000/Bag
Jensen Global JG22-1.25TT, 22 Gauge 1.25 in IT Series Tapered Dispensing Tip, 1000/Bag
The Jensen Global JG22-1.25TT is a blue, 22-gauge IT Series tapered dispensing tip supplied in a bag of 1,000. Its 1.25-inch all-plastic polypropylene design provides a tapered fluid path intended to reduce backpressure when dispensing medium- to high-viscosity materials.
Jensen specifies a 0.017-inch (0.430 mm) inside opening for this exact ordering code. Select the tip using that opening, the overall geometry and the fluid requirements rather than assuming that matching gauge numbers make straight and tapered tips interchangeable.
Key Features
- 22-gauge IT Series tapered tip with blue color identification.
- All-plastic polypropylene construction with a high-density molded tapered design.
- Double-helix threaded connection.
- 1.25-inch length and 0.017-inch (0.430 mm) opening.
- Tapered flow path designed to reduce backpressure with medium- to high-viscosity materials.
- Plastic contact surface offered by Jensen for sensitive-part applications; validate actual surface interaction in your process.
- Bulk bag containing 1,000 tips.

Best Uses / Applications
Evaluate this tip for industrial adhesive and assembly-fluid dispensing when a tapered fluid path is preferable to a long narrow straight cannula. Potential applications include component bonding, controlled bead application and bench dispensing of compatible viscous formulations.
For electronics assembly or precision bonding, check the required deposit, stand-off and clearance around the joint. The tapered body needs different access than a slender metal cannula. Confirm material compatibility and any particle-size requirements with the fluid supplier; this tip is not automatically suitable for every filled paste, adhesive or sealant.
Compare Dispensing Tip Designs
| Design | Why evaluate it? | Selection check |
|---|---|---|
| JG22-1.25TT tapered polypropylene | Tapered internal path intended to reduce backpressure with medium- to high-viscosity materials. | 0.017-inch outlet, body clearance, fluid compatibility and deposit repeatability. |
| Straight stainless steel cannula | A narrow external profile may suit restricted access. | Actual bore and length; gauge alone does not establish equivalent flow. |
| Flexible plastic tip | An alternative contact material and stiffness. | Deflection, positioning stability and chemical compatibility. |
Ordering and Process Guidance
JG22-1.25TT is the bag-of-1,000 ordering code. Jensen lists JG22-1.25TTX separately as a box of 50. Match the full code and packaging when placing an order or approving a substitute.
Confirm the mating connection and operating limits with the dispensing-equipment manufacturer. Trial the actual fluid under its specified handling conditions, then measure the deposit at start-up, during steady operation and after representative pauses. Do not use a pressure increase as a substitute for investigating blockage, fluid condition or an unsuitable flow path.
Jensen describes this plastic design as offering scratch-free protection for sensitive parts. That does not guarantee that every contact process is damage-free: inspect for debris, damage and excessive contact force, and validate on representative surfaces. Plastic construction alone also does not establish ESD suitability or cleanroom qualification.
Frequently Asked Questions
What is the inside opening of JG22-1.25TT?
Jensen’s exact JG22-1.25TT variant specifies 0.017 inch (0.430 mm). Use this exact-series specification rather than transferring dimensions from another 22-gauge design.
How many tips are included?
This listing is for a bag of 1,000 tips. The manufacturer’s JG22-1.25TTX code is the box-of-50 option, not the configuration sold here.
Why choose a tapered tip instead of a straight metal tip?
The tapered plastic flow path is designed to reduce backpressure for medium- to high-viscosity materials. A straight tip may provide different access or flow behavior. Compare actual geometry and trial the formulation before substituting.
Is the tip made from stainless steel?
No. This IT Series tapered design is all-plastic polypropylene, unlike the stainless steel cannula used in Jensen’s standard straight-tip family.
Does 22 gauge guarantee a particular dot size?
No. Deposit size also depends on the fluid, dispense timing, pressure, stand-off, movement and receiving surface. Establish a process window by testing rather than gauge alone.
Will the plastic tip prevent all scratching?
No universal no-scratch guarantee applies to your assembly. Jensen offers the design for sensitive-part applications, but contamination, force and outlet damage still need controlling.
Can I use it with any viscous or particle-filled adhesive?
No. Check chemical compatibility, particle loading, working life and the opening required by the exact formulation. Medium-to-high viscosity is a selection guideline, not a universal approval.
