PVC Y-Fitting ID 20~63mm White Blue Grey PVC Y-Type Pipe Fitting Split Fittings

Match the fitting's Inside Diameter (ID) to your pipe's Outside Diameter (OD). For standard Schedule 40 PVC, a 20 mm ID fitting suits ¾" pipe, 25 mm suits 1", 32 mm suits 1¼", 40 mm suits 1½", 50 mm suits 2", and 63 mm suits 2½". When in doubt, dry-fit the pipe into the socket before cementing — it should slide in with light hand pressure and stop at the socket shoulder.

Pressure ratings vary by size and wall thickness. Smaller diameters (20–32 mm) typically handle higher working pressures than larger sizes (50–63 mm) at the same wall thickness. For confirmed pressure ratings for your specific size, please refer to the variant options or contact us to confirm before use in pressurized systems.

Yes. Rigid PVC is inherently resistant to rust, corrosion, and a wide range of chemicals including chlorinated tap water, fertilizer solutions, and mild acids or bases commonly used in irrigation and aquaponics systems. It is not recommended for concentrated solvents, aromatic hydrocarbons, or high-temperature fluids above approximately 60 °C (140 °F).

No. These fittings are rated for cold water and ambient-temperature service only. PVC softens and loses structural integrity at elevated temperatures. For hot water applications, use CPVC or other heat-rated fittings instead.

The listed inside diameters (20, 25, 32, 40, 50, 63 mm) correspond to common metric pipe sizes used in many regions. However, pipe OD standards can vary by country and manufacturer. We recommend dry-fitting a sample before cementing to confirm compatibility with your specific pipe stock.

Use a standard PVC solvent cement (PVC glue) appropriate for the pipe diameter. For larger sizes (40 mm and above), a medium- or heavy-bodied cement with a PVC primer is recommended for a stronger, faster-curing bond. Always follow the cement manufacturer's cure time before pressurizing the joint.

A Y-type (wye) fitting branches at an angle rather than 90°, which produces a smoother flow transition and lower turbulence at the split point. This makes Y-fittings preferable for drainage runs (where flow direction matters) and for irrigation manifolds where maintaining consistent pressure across both outlet legs is important.
