Product overview
Spigot joint (rubber-seal bell and spigot) for fiberglass GRE/FRP pipe: the plain spigot end seats into the bell with a compressed rubber gasket. Non-restrained — plan thrust blocks at bends, tees and dead ends, or specify a locked joint where restraint is required.
Provide the pipe schedule and layout so sealing, movement and thrust-management requirements can be reviewed together. Manufactured at the licensed partner factory; drawings and datasheets issued against your RFQ.
Information for selection
- Pipe and mating component drawings, dimensions and joint type.
- Fluid, design pressure and temperature, supports and installation arrangement.
- Fitting schedule, quantities, inspection requirements and delivery destination.
Configuration and technical documents
Request the drawing and technical data for the exact configuration offered. Confirm material compatibility, dimensions, connection details and the conditions applicable to any published rating before ordering.
Supports, anchors and thrust management must be reviewed for the complete pipeline layout. A joint designation alone does not determine every installation requirement.
Request a quotation
Send your project requirements, together with quantity and delivery destination. List the pipe body, fittings, accessories and documentation you need included in the quotation.
A technical datasheet is not published on this page. Request the applicable dimensions, ratings and supporting documents for your project. Request the product datasheet.
Technical documents
Request the product datasheet, connection information and qualification documents needed for your project. Our team will confirm document availability and the applicable version.
What is a spigot joint?
A spigot joint (bell & spigot joint) connects two pipe lengths by fitting the plain spigot end of one length into the enlarged bell socket of the next. In IFGS fiberglass pipe, a compressed rubber gasket inside the bell forms the watertight seal. The joint is non-restrained, so bends, tees and dead ends need thrust blocks or a locked joint.
Joint types compared
| Joint type | Seal | Restraint | Typical use |
|---|---|---|---|
| Rubber-seal bell & spigot | Rubber gasket | Non-restrained (thrust blocks required) | Long straight runs; up to 1,400 mm / 50 bar |
| Adhesive-bonded (cemented) | Resin bond | Permanent, non-removable | Permanent lines where disassembly is not expected |
| Locked (restrained) joint | Rubber gasket + lock | Restrained | Bends, tees and dead ends without thrust blocks |
Frequently asked questions
What is the difference between rubber-seal and adhesive-bonded bell and spigot joints?
A rubber-seal joint uses a compressed rubber gasket inside the bell and remains non-restrained, allowing disassembly and some deflection. An adhesive-bonded (cemented) joint joins the spigot and bell permanently with resin and cannot be taken apart.
What sizes and pressures are available for IFGS rubber-seal bell and spigot joints?
IFGS rubber-seal bell and spigot joints are produced up to 1,400 mm in diameter and up to 50 bar working pressure. Confirm the size, rating and deflection limits for your application with IFGS.
Do rubber-seal bell and spigot joints need thrust blocks?
Yes. A rubber-seal bell and spigot joint is non-restrained, so thrust forces at bends, tees and dead ends must be carried by thrust blocks, or the joint converted to a restrained (locked) design.
