Customized PVC & uPVC Fittings
Manufacturer in Saudi Arabia
4B Factory fabricates custom PVC and uPVC fittings from 20 mm to 315 mm at our Al-Kharj Industrial District facility — including long bends, repair couplings, register couplings, flanged sockets, flanged spigots, and sleeve ends. Built to project specification with pressure ratings up to 16 Bar, for water, sewer, conduit, and industrial pipeline projects across Saudi Arabia.

Custom Fittings When Standard Catalogue Items Don't Fit Your Project
Every pipeline project eventually needs a fitting that isn’t in any standard catalogue — an odd-angle bend, a non-standard size repair coupling, a flanged spigot to match an existing flange, a register coupling for a specific tie-in. Off-the-shelf doesn’t fit. Imported takes weeks.
4B Factory fabricates these fittings from our own extruded uPVC pipe stock — matching the pipe material, standard, and pressure rating of your line. Faster lead times than imports, factory-direct pricing, and full traceability since the fitting comes from the same compound batch as the pipe.

Fitting Types, Sizes & Pressure Ratings
Our custom fittings cover the full diameter range of our pipe production, in all common jointing systems and pressure classes Saudi water authorities and contractors specify.

Rubber Ring vs Solvent Weld — Which Joint Type?
Custom fittings are produced in two jointing systems matching the parent pipeline. Choose based on diameter, pressure class, and field installation method.
Rubber Ring Jointing (R/J)
Push-fit assembly sealed with an EPDM elastomeric ring factory-formed into the socket. Preferred for larger diameters (≥ 110 mm), pressure pipelines, and applications where some thermal movement is expected. Faster field installation than solvent — no curing time, no chemicals on site.
Solvent Weld Jointing (S/W)
Chemically bonded permanent joint using PVC solvent cement. Used for smaller diameters, fully sealed applications, and where the joint must resist any pull-out force. Standard method for ASTM D1785 pipe fittings and most conduit applications.
Custom fittings are produced matching the joint type and pressure class of the parent pipe — so an R/J 200 mm Class 5 watermain gets an R/J 200 mm Class 5 bend, with the same wall thickness, same socket geometry, and same compliance documentation. For specific Loc-Ring socket fittings, see our PVC Fabricated Products page.
Applications Across Saudi Arabia
Our custom fittings are installed across the Kingdom wherever the pipeline needs something a catalogue can’t supply.
NWC Network Tie-Ins
Custom register couplings and flanged spigots for tying new watermain branches into existing NWC infrastructure.
Emergency Repair Couplings
Same-day or next-day fabrication of repair couplings for water network leak response and outage management.
Sewer Network Bends
Custom-angle long-radius bends for sewer alignment changes — 11.25°, 22.5°, 45° and any project-specific angle.
Industrial Pipeline Adapters
Flanged sockets and spigots for connecting PVC lines to metal equipment in industrial plants and treatment works.
Watermain Custom Angles
Long bends produced to match site layout where standard 45° or 90° doesn't fit field alignment.
Tender-Specific Fittings
Project-specified fittings matched to consultant drawings — fabricated and certified to match parent pipe.
Conduit Junction Fittings
Custom adapters and junctions where NEMA TC 2 catalogue items don't match the layout.
Compound & Building MEP
Project-specific fittings for compound water networks, building risers, and MEP installations.
Bulk Supply & Project-Specific Fabrication
4B Factory routinely fabricates custom fittings for major Saudi pipeline programmes alongside our standard pipe deliveries. Our team works directly from your project drawings, bill of quantities, or technical specifications — issuing formal quotations with full compliance documentation and project-scheduled delivery.
Frequently Asked Questions
Common questions from contractors, MEP engineers, and procurement teams sourcing uPVC duct pipes in Saudi Arabia.
At minimum: pipe size and standard, pressure class, joint type (R/J or S/W), fitting type, dimensions or drawing. For complex fittings, a sketch or PDF drawing is ideal. Our technical team will confirm specs and issue a formal quotation.
Standard custom configurations (e.g., non-standard bend angle in a stock size): typically 3–7 working days. Complex or large-volume fabrications: 1–3 weeks depending on quantity and complexity. Emergency repair couplings: same-day or next-day where possible. Confirmed lead times come with each formal quotation.
6, 9, 10, 12, and 16 Bar depending on the parent pipe specification. The fitting is fabricated from the same pipe stock as your pipeline — so a 16 Bar pipeline gets 16 Bar fittings, with matching compliance documentation.
Yes — we produce flanged sockets and flanged spigots to common flange standards (ISO PN, ANSI/ASME, DIN). Specify the flange standard and drilling pattern in your enquiry; we’ll match it.
Yes. Because they’re fabricated from our own extruded pipe stock, custom fittings inherit the same material certifications, test reports, and standards compliance as the parent pipe. Submittal-ready documentation supplied with every order.
Up to 315 mm (12″) diameter in our standard custom range. For larger fittings on major infrastructure projects, contact our technical team to discuss feasibility.
Yes — emergency repair coupling fabrication is one of our regular service categories. With your existing pipe specifications and site dimensions, we can typically produce and dispatch within 24–48 hours.
Yes — fittings matching ASTM D1785 Schedule 40 and Schedule 80 systems are produced from compatible pipe stock with solvent weld jointing. See our PVC ASTM Standard Pipes page for parent pipe specifications.
