Plastic Ball Socket – Type PL2 – Extended Version
The extended PL2 is a plastic ball socket with a brass threaded insert and a spring retaining clip, used in gas spring assemblies and other mechanical connections requiring angular movement. It connects to a compatible ball stud with a nominal ball diameter of 10 mm and can also be used with our brackets fitted with compatible ball studs.
The internal thread connects the socket to a threaded component of the gas spring or another assembly. A spring retaining clip secures the ball stud in the socket while allowing angular movement within the limits of the assembled connection. When selecting a socket, check that its mating dimensions are compatible with the ball stud and allow the required movement.
Compared with the standard PL2, the extended body provides a neater appearance at the connection to the gas spring cylinder. The listed variant, PL210216M, has an M6 internal thread in a brass insert. The technical drawing shows its dimensions and construction.

Extended PL2 Plastic Ball Socket – Dimensions and Variants
The dimensional table lists the PL210216M product code, internal thread size and installation dimensions. The corresponding technical drawing provides the detailed dimensions needed to check compatibility with your application.
When selecting the socket, check the 10 mm nominal ball diameter, M6 internal thread and installation dimension l2 of 21 mm. Dimension l2 is measured from the centre of the ball socket to its threaded end face, as shown in the drawing. The overall length l1 is 29.5 mm, compared with 26.5 mm for the standard PL2.
For use with one of our brackets with a ball stud, also check the available clearance and required range of movement.
Materials and Available Versions
The extended PL2 ball socket has a black PA66 GF30 body — polyamide 66 reinforced with 30% glass fibre — and a brass threaded insert. The spring retaining clip is made from CK67 spring steel with a black zinc-plated finish.
The listed PL210216M variant has an M6 internal thread. Please refer to the dimensional table and the corresponding drawing for its specifications.
Need Help Selecting an Extended PL2 Ball Socket?
If you are unsure whether the extended PL2 is suitable for your application, send us the nominal ball diameter, internal thread size, installation dimensions and quantity. Please indicate whether the socket will be used with a separate ball stud or one of our brackets with a ball stud, and whether it will be fitted at the cylinder end of the gas spring. If available, include the dimensions or product code of the mating component.
Send us a drawing, photo, dimensions and application requirements. Our team can help check whether the extended PL2 is compatible with the mating component and the available installation space.
