Pneumatic And Battery Guns
JS8625-A 9-inch pneumatic caulking gun (for 300ml silicone bottles)
A 9 inch pneumatic gun for 300 ml silicone bottles at 500 g, with a 350 KG frame tolerance.
Product Overview
A 9 inch pneumatic gun for 300 ml silicone bottles at 500 g, with a 350 KG frame tolerance. Push force and drive ratio are set on the gun's own regulating valve rather than fixed, so one tool covers products of different viscosity. It runs off a shop air hose, which removes trigger effort from the job entirely.
Key benefits
Why Buyers Choose This Model
Output Set At The Valve
An adjustable valve controls dispensing ratio and speed, so push force and drive ratio change with the setting instead of being fixed at manufacture. One gun covers thin and stiff product.
500 g, The Lightest Pneumatic
The 9 inch model is the lightest of the three pneumatic guns, which matters because an air hose is already adding weight and drag.
350 KG Frame Tolerance
The frame is rated well above anything the valve will deliver in normal use, so the limiting factor is the air supply rather than the gun.
Uniform Bead Regardless Of Operator
Because the output is set mechanically, every unit on a line gets the same bead, which is the main reason a factory buys pneumatic rather than manual.
Application scenarios
Where It Is Used
- Production line adhesive dosing with shop air available
- Repeat glazing operations in a window plant
- Long runs where bead consistency is inspected
- Workshops running 300 ml cartridges at volume
Who it is for
The Buyers This Model Suits
Factory Assembly Lines
Has compressed air already and needs repeatable volume on every unit rather than operator-dependent output.
Window And Door Fabricators
Glazes hundreds of units and cannot absorb the labour cost of manual trigger effort.
Finishing Shops
Works to a visual standard where an uneven bead is a reject rather than a cosmetic note.
Problems it solves
What It Fixes
Operator Fatigue Setting The Pace
On a production line a manual gun makes output a function of who is on shift. Air removes that variable.
One Gun, Several Products
The regulating valve means the same tool suits different viscosities without buying a second gun.
Bead Consistency As A Quality Metric
A fixed valve setting delivers the same volume every time, which is what an inspection standard actually needs.
Technical features
How It Is Built
Pneumatic Operation
This silicone gun operates pneumatically, requiring connection to an air hose to dispense silicone smoothly and effortlessly.
Adjustable Valve
Equipped with an adjustable valve, you can precisely control the dispensing ratio and speed, providing optimal control during the application process.
Efficiency
The pneumatic mechanism ensures high efficiency, making it an ideal choice for professional construction projects where speed and precision are crucial.
Uniform and Neat Dispensing
The JS8625-A silicone gun ensures uniform and neat dispensing of silicone, contributing to a more professional appearance during construction.
P rofessional Construction
Customized for professional construction tasks, the JS8625-A can withstand demanding work environments and deliver consistent results.
Easy to Use
Ergonomic design and pneumatic operation make the silicone gun easy to use, reducing operator fatigue during prolonged use.

Materials and manufacturing
How This Model Is Made
Parts for the JS8625-A are produced in our own workshops in Jinli Town, Zhaoqing. This model uses both routes: its moulded components come off our five horizontal and three vertical injection moulding machines, and its metal parts come off our fifteen automatic punching machines, nine automatic lathes and three welding machines. Tooling is designed and cut in our own mould room, which is why a change to this model does not queue behind another factory's schedule.
Quality Control
- Every model is weighed against its declared net weight during production, so the carton weight on your packing list matches what arrives.
- Stamped parts are produced in house on 15 automatic punching machines and 9 automatic lathes, so dimensional consistency is controlled at source rather than inspected on arrival.
- Moulded parts come off 5 horizontal and 3 vertical injection moulding machines running up to 10,000 mould open-and-close cycles per day, with tooling maintained in our own mould room.
- The quality management system was certified to ISO 9001:2015 in August 2023, with a certificate valid to 31 July 2026.
- Cartons are counted against the packing list as they are loaded into the container at our own factory door.
Certifications
The quality management system was certified to ISO 9001:2015 in August 2023, under standard GB/T19001-2016, for the manufacture and sale of glass caulking guns and sealant guns. The certificate on file runs to 31 July 2026; ask us for the current renewal status before relying on it. A TUV Rheinland assessment was obtained in 2016.
Customisation Options
- Aluminium Tube Anodizing And Colouring: More than 10 colours available; the surface can be given a frosted texture.
- Aluminium Tube Painting: Up to 10 colours with customisable patterns.
- Aluminium Tube Laser Engraving: Engraved logos, text and patterns on stamped fittings and aluminium tubes.
- Self-Adhesive Logo Labels: Applied to the product in the position the buyer specifies.
- Multi-Colour Logo Printing: Paint screen printing in any colour, with several colours printed at once.
- Tag And Product Screen Printing: Screen printed tags and product markings, multi-colour capable.

Getting The Best Out Of It
Step 1
Connect to the shop air hose and set the regulating valve low before the first trigger pull.
Step 2
Test on scrap and raise the valve setting until the bead is right for the product.
Step 3
Keep the valve setting logged per product, so the next operator starts where the last one finished.
Step 4
Disconnect the air before changing a cartridge, and drain moisture from the line regularly.
Comparison
How It Compares In Our Range
Three pneumatic models, differing in barrel length and frame tolerance.
| JS8625-B | 15 inch at 600 g with the same 350 KG tolerance, for 400 ml and longer packs. |
|---|---|
| JS8625-C | 18 inch at 750 g with a higher 400 KG tolerance, the largest pneumatic here. |
| JS862X-1500mA | The battery alternative at 4000 N thrust, if there is no air supply. |
FAQ
JS8625-A Questions
What air pressure does it need?
Output is set on the gun's own regulating valve rather than by a specified supply pressure, and our published materials do not state a required figure. Ask us before you specify a compressor for it.
What is the push force?
Push force and drive ratio both change according to the regulating valve setting, so no fixed figure applies. The frame tolerance is 350 KG, which is the limit that does not change.
What pack does it take?
300 ml silicone bottles, which is why the barrel is 9 inch. The 15 and 18 inch models take longer packs.
What colour is stock?
Frosted purple, with custom colours available. Minimum order 1,000 pieces.
How is it packed?
One piece per inner box, 20 pieces per master carton at 52 x 55 x 45 cm.
