Pneumatic And Battery Guns
JS8625-C 18-inch pneumatic silicone gun
The largest pneumatic gun in the range: 18 inch, 750 g, with a 400 KG frame tolerance, the highest of the three.
Product Overview
The largest pneumatic gun in the range: 18 inch, 750 g, with a 400 KG frame tolerance, the highest of the three. The adjustable valve sets dispensing ratio and speed, and the ergonomic body is built to reduce operator fatigue through prolonged use, which at this barrel length is the design constraint.
Key benefits
Why Buyers Choose This Model
400 KG Frame Tolerance
The highest of the pneumatic models, 50 KG above the 9 and 15 inch versions. At this barrel length the frame carries more leverage, and the rating reflects it.
18 Inch Barrel
Takes the longest packs and reaches furthest into a joint, for professional construction work where access is from a distance.
Adjustable Dispensing Valve
Precise control of ratio and speed at the valve, which is what makes uniform and aesthetically even dispensing achievable at this scale.
Built For Prolonged Use
The ergonomic design and pneumatic operation are specified to reduce operator fatigue over long sessions, which is the point of a powered gun.
Application scenarios
Where It Is Used
- Long continuous joints in professional construction
- Large-format sealing where reach matters
- Work needing the highest pneumatic frame rating
- Production environments running the longest packs
Who it is for
The Buyers This Model Suits
Professional Construction Crews
Runs long joints where speed and accuracy are both being judged and a manual gun cannot sustain either.
Large-Format Fabricators
Works on panels and assemblies where the operator needs reach as well as output.
Buyers Specifying On Frame Rating
Wants the highest tolerance figure in the pneumatic range.
Problems it solves
What It Fixes
Reach On Large Assemblies
18 inch puts the nozzle where a 9 inch gun cannot, without the operator repositioning.
Leverage On A Long Barrel
The 400 KG tolerance is the answer to the extra bending load a long barrel creates.
Fatigue On Extended Sessions
Pneumatic operation plus ergonomic design is specified for exactly the sessions that would break a manual crew.

Materials and manufacturing
How This Model Is Made
Parts for the JS8625-C 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 the air hose and start with the regulating valve at its lowest setting.
Step 2
Support the barrel with the free hand on a gun this length, particularly overhead.
Step 3
Test and record the valve setting per product before production starts.
Step 4
Disconnect air before loading a pack, and drain the air line of moisture regularly.

|---|---|
| JS8625-A | 9 inch at 500 g for 300 ml bottles, the lightest option. |
| JS862X-3000mA | The cordless alternative at 6500 N thrust, where no air line reaches. |
FAQ
JS8625-C Questions
Why is the tolerance higher than the shorter models?
A longer barrel creates more bending leverage on the frame, so the frame is rated higher: 400 KG against 350 KG on the 9 and 15 inch.
What is the push force?
It changes according to the regulating valve setting, so no fixed figure is published. The 400 KG frame tolerance is the fixed limit.
Is it too heavy for site work?
At 750 g it is the heaviest pneumatic here, and with an air hose attached it is a two-handed tool on extended work. For site work without air, consider the JS862X battery guns.
What colour is stock?
Frosted purple, with custom colours available. Minimum order 1,000 pieces.
How is it packed?
One piece per inner box, 12 pieces per master carton at 52 x 55 x 45 cm.
