4" to 1" PVC Pipe Reducer
This PVCReduce page is for a custom 4" to 1" PVC pipe reducer. Enter those diameters in the configurator above (or fine-tune nozzle heights and wall thickness) to order a part sized for your exact pair—not a nearest off-the-shelf compromise.
A 4" → 1" transition spans 81mm between ends and is commonly used for pool equipment, irrigation manifolds, and general plumbing transitions. Measure inside and outside diameters carefully before checkout so the digital STL matches the pipes you already have.
Order a digital STL (€3.99) and print the reducer locally in any compatible material. PVCReduce delivers the file by email — there is no physical shipment.

Frequently asked questions
How should I measure pipes for a 4" to 1" reducer?
Measure the actual inside diameter (ID) and outside diameter (OD) of each pipe with calipers when possible. Nominal labels can differ from real dimensions—confirm both ends before ordering this 4" → 1" pair. See the pipe measurement guide for a step-by-step approach.
What do I receive after checkout?
A production-ready digital STL (€3.99) delivered by email. You print the reducer yourself on a compatible 3D printer. PVCReduce does not ship a physical part.
Which material should I print in?
PETG is a common choice for pipe transitions because it balances strength, chemical resistance, and dimensional stability. The STL can be printed in any compatible material or colour your printer supports.
Can I resell the STL file?
No. The digital STL is licensed for your personal or internal project use only. You may print parts for yourself, but you may not redistribute, resell, or share the STL file.
How is the file delivered?
After payment, the STL is generated and emailed to you. Download links remain active for 14 days. There is no postal shipping.
