Glued PVC drainage fittings for solvent weld systems
Glued PVC drainage fittings connect PVC-U drainage pipework in solvent weld drainage systems. They are used in drainage, sewage and rainwater layouts where pipe direction, branching, reduction, repair or closure is needed. Products are mainly grey PVC-U fittings with glue socket, glue spigot, glue socket x spigot or related glued connection formats.
PVC solvent weld fittings are selected by fitting type, diameter, angle and connection. Matching these details helps create a compatible pipe layout and avoids mixing fittings with the wrong end connection. Common visible sizes include 32 mm, 40 mm, 50 mm, 75 mm, 80 mm, 110 mm, 125 mm, 160 mm and 250 mm, depending on the fitting type.
Choosing the right PVC solvent weld fitting
The first choice is usually the function of the fitting. Direction changes call for PVC drainage elbows and bends. Branching pipework needs T-pieces or reducer T-pieces. Straight connections, repairs and transitions use sockets, repair sockets, sliding sockets or reducer bushes. End closures use plugs, caps or end sets.
Angles are a key selection point for PVC drainage elbows and T-pieces. Visible options include 22°, 45°, 67°, 87°, 87.5° and 90° fittings. A bend changes the route of a pipe, while a T-piece creates a branch. For a clean installation, match the angle to the pipe run before choosing the diameter and connection.
Bends, elbows and T-pieces
For changes in direction, solvent weld pipe fittings such as 45°, 87° and 90° bends are available with glue socket or glue socket x spigot formats. A glue socket connection is used where the pipe or fitting end is designed for solvent welding into the socket. A glue socket x spigot format combines a socket end with a spigot end for layouts that need that connection arrangement.
Branching layouts use PVC drainage T-pieces. Options include standard T-pieces, reducer T-pieces and inspection T-pieces. Visible product variants include 45°, 87°, 87.5° and 90° versions, as well as reducing combinations such as 75 mm x 50 mm x 75 mm and 110 mm x 50 mm x 110 mm.
Sockets, bushes and repair fittings
PVC drainage couplings, sockets and bushes support straight pipe connections, size changes and repair work. Visible options include drainage sockets, repair sockets, sliding sockets and reducer bushes. Connection descriptions include glue socket, glue socket x spigot, glue socket x insert and glue socket x ring seal.
Reducer bushes are used where the pipe layout requires different diameters to be joined. Repair sockets and sliding sockets help when working with existing pipework, provided the selected diameter and end connection match the installation. Always check the exact size combination stated for the fitting, especially where multiple diameters appear in the same product name.
Closures, saddles and accessories
End closures are covered by drainage caps, plugs and end sets. Plugs, caps and nuts are practical when a pipe end or access point needs to be closed with a compatible fitting. Visible products include PVC-U glue socket caps, PVC-U glue socket or glue spigot plugs and PVC-U glue spigot end sets.
Drainage saddles are available for specific branch connections. A visible example is a PVC-U clamp saddle with glue saddle x glue socket connection. Match the saddle size and outlet size to the pipework, as saddle fittings often carry more than one diameter in the product description.
Some related accessories use other materials or connection styles, such as PE mortar caps and PVC elastomer flexible sockets with clamp connections. When selecting PVC sewage fittings or underground drainage fittings, check the material, colour, size and connection format to avoid mixing glued PVC-U fittings with flexible or ring seal formats where they are not intended to be combined.
Practical selection checks
Start with the pipe diameter, then select the fitting type and angle. After that, confirm the end connection, such as glue socket, glue spigot, glue socket x spigot or glue saddle x glue socket. If a project requires a stated approval or marking, choose only products where that marking is present, such as items marked KOMO.
PVC-U glued fittings work best when each part of the drainage layout is planned before ordering. Check every branch, change of direction, reducer, repair point and end closure as part of the same solvent weld drainage system. Careful matching of size and connection keeps the installation consistent from the first fitting to the final cap.
