Trelleborg 101 G-Ring is a compression seal which is rolled into place during joint assembly.
The seal is designed, primarily, for non-pressure concrete pipelines, but if the joint is correctly designed, it can also be used for pressure pipelines. The compression of the seal varies according to the joint gap and tolerance chosen.
This joint design is standard in many countries.
Joint performance is dependent on dimensional accuracy and surface finish of socket and spigot.
Trelleborg 101 G-Ring seal meets all relevant current European standards.
Key features & benefits
- Increased stability on spigot during pipe centering and jointing
- The teardrop shaped profile prevents the pipes from separating once jointed
- Suitable for low pressure pipelines
Material
- Synthetic SBR or EPDM rubber - Hardness 40±5 IRHD
- Approved in accordance with EN 681-1
- Protected against ozone, oil resistant grades are available on request

Dimensions & Designation
On each seal, profile thickness, outer diameter, recommended pipe measurement and production period are given. The corresponding data are also on the packaging.
Subject to change for technical reasons.
Joint Assembly
Ensure both spigot and socket are clean. Stretch the seal onto the spigot with the point of the G-ring facing outward.
Equalize the stress in the seal by lifting and realising at a few point. The sealmust sit evenly all around the pipe.
Centre the pipes and assemble by using suitable equipment. The G-ring will roll over and seat itself in the socket.
