Profile and certifications

Leader for 50 years in the production of gas springs, dampers and decelerators.

Vapsint started off in the sixties, as VAP Veneta Ammortizzatori, a workshop specialized in the production of regenerated dampers for motorvehicles and the marketing of spare parts for the car industry. In the seventies it began producing the first gas springs for motorvehicles. In the eighties the production became industrialized, as gas springs met with increasing use and interest in many market areas: engineering, food, furniture, marine…
The Company has developed over the years new products that, in addition to gas springs and their numerous versions, deal in different ways with the movement and weight of objects: adjustable decelerators, hydraulic dampers, as well as dampers for industrial applications.

A reference point for furniture, automotive, marine, pharmaceutical and food industries.

The technical knowledge of materials, the constant research and experimentation, the attention to clients and their needs, and the variety of customized solutions make Vapsint a point of reference for many companies. The close collaboration with clients in the design and planning of new applications allows Vapsint to provide the best solution for every specific requirement. CAD drafting technologies and three dimensional simulation models lead to a better understanding of product application.

Experience, technology, certifications.

Vapsint developed and certified a quality system complying with the UNI EN ISO 9001 standard. Product quality and client satisfaction are a prime point in the Company’s mission.

Fields of application: furniture, automotive, industry, medical, foodservice equipment, marine.

Vapsint manufactures standard products for many sectors, including the furniture and industrial sector. It also develops customized products upon clients specific indications, defining new production standards and widening the range of products on offer.

Here is a list of products currently being manufactured by Vapsint, divided by categories:


Force | Differentiated Force | Frictioned | Hydro Pneumatic with hard damping | Dynamic damping | with AntiTear system | with Locking tube | with Protection tube


Elastic Locking | Rigid locking in Extension | Rigid locking in Compression | Rigid locking with the lowest progression (Flat Curve) | Lock in the fully opened position (Lock Out) | Lock in the fully closed position (Lock In); Mechanical Lock on the piston rod


Damping during compression | Damping during extension | Dual effect


AISI 304 | AISI 316


For motorvehicles | For industrial applications


with Fixed Setting (Heavy Duty Dampers) | with Adjustable Setting (AS Series)


Standard gas springs are matt black but they may be supplied, on request, in other colors.

The rod is made of treated steel hardened by chrome plating.

The table below reports the main measurements, strokes and minimum and maximum forces of standard gas springs together with the progression percentage which indicates the difference in force between fully opened (F1) and fully closed (F2) position.

How to read a gas spring‘s code?

apsint code is generally divided into groups of number like: XX XX. XXXX. XXX-XXX/XXX

EXAMPLE: 19 8. 600. 35- Rs2/Tz

The “198” group refers to the combination between the gas springs cylinder (body) and the piston rod. The most diffused combinations are 15 6; 19 8; 22 10; 28 10; 28 14. Coming back to the example 198 = Cylinder diameter 19 mm. and Piston Rod diameter of 8 mm..

The “600” group refers to the lenght (between holes center or ball joints centers) of the gas spring in the fully opened position. In our example 600 means 600 mm. between holes centers.

The “35” group indicate the force of the gas springs expressed in kilograms. To obtain the newton force multiply it by 10. In our example 35= 35 kg. of force 350N (measured with the piston rod compressed of 10 mm.)

The “Rs/Tz” group identify the code of the attachments. The first indicates the attachment on the cylinder and the second the attachment on the piston rod. In the example Rs2 is the cylinder attachment and TZ is the piston rod attachment:


The code has to be read like: gas springs with a cylinder of 15 mm. diameter and piston rod of 6 mm. diameter. Lenght between holes center of 247 mm. and force of 15 kg. (150N) with TSNS attachment on the cylinder and TSNS on the piston rod.

P.S.: if you are looking for a spare part it is mandatory to communicate the code written on the lable together with the name of the application and the date of production.
