These premium rubber pipe seal grommets provide a heavy duty, watertight mechanical connection designed for running plastic drainage pipework directly into pump chambers, sewage treatment plants, or subterranean manhole structures.
Engineered to accommodate both prefabricated and core drilled entry points, these robust elastomeric seals ensure a flexible, watertight joint where rigid pipelines penetrate tank walls.
Details
Performance
By allowing for minor structural movement and settling without breaking the pressure seal, they deliver long term protection against groundwater infiltration and external fluid leaks in demanding civil engineering and domestic drainage layouts.
Featuring an advanced triple lip internal sealing profile, the design allows for effortless pipe insertion on site while offering superior resistance to transverse shear loads and soil movement.
This unique flexibility permits a high degree of angular deflection within the pipe joint, making it an indispensable accessory for groundworkers connecting inbound gravity lines or outbound discharge pipework to plastic and concrete chambers.
Available in industry standard diameters from 110mm up to 250mm, these grommets accommodate all common underground drainage variants including smooth walled PVC and ribbed twin wall systems.

Highlights
The advanced triple lip seal profile creates a heavy duty compression barrier that effortlessly absorbs pipe vibration and structural ground deflection while preventing soil or water ingress
Manufactured from a durable synthetic rubber compound that provides excellent resistance against biological degradation, chemical contact, and common chemical contaminants found within residential wastewater systems
Perfectly compatible with both smooth walled plastic drainage lines and standard corrugated twin wall ducting pipework to offer complete flexibility across varied installations
The highly flexible composition allows installers to accommodate angular joint deflection during final pipe alignment without distorting the internal sealing lips or compromising joint integrity
Provides a reliable watertight fitment when paired with precision core drilled apertures or factory moulded tank inlets to dramatically reduce installation times on site
