Storm PVC Coupling Slip 90 mm

The Storm PVC Coupling Slip 90 mm is a precision-engineered fitting ideal for joining two sections of 90 mm stormwater PVC-U pipe, especially suited to tight installation zones or pipe repairs requiring flexibility.

Overview & Functionality

Slip (repair) coupling: featuring female sockets on both ends, with no internal stop or register, allowing the fitting to slide over pipe ends before positioning and jointing securely.
Solvent cement joint (SWJ): provides a watertight, permanent connection once set.

Material & Compliance

Constructed from durable PVC-U, ensuring corrosion resistance and long-term service life.
Compliant with AS/NZS 1254, the standard for stormwater PVC fittings in Australia/New Zealand.

Applications & Advantages

Ideal for in-situ pipe repairs, extending existing runs, or connecting aligned pipes where cutting or shifting is impractical.
Eliminates the need to precisely align two pipe ends before coupling—simply slide the coupling over and shift into position before applying solvent cement.

Available Variants & Examples

Installation & Usage Tips

Cut and clean pipe ends, slide coupling over one section, then align second pipe and slide coupling over joint area.
Apply PVC solvent cement within sockets and spigots, assemble quickly before cement sets.
Once assembled, allow curing time (~24 hours) before testing or backfilling.
Avoid adjusting the coupling once solvent is applied—it bonds firmly and adjustments may compromise seal.
