- Product Range
Types of PPR Fittings
AquaTerra’s full range covers every connection requirement — from directional changes and branch connections to pressure-rated valves and threaded transitions.
- Direction Change
90° Elbow
Creates a right-angle turn in the pipeline. The most common PPR fitting for routing pipes around walls, ceilings, and structural elements without restricting flow.
- Direction Change
45° Elbow
Provides a gentle 45-degree directional change, reducing turbulence and flow resistance in long-run hot and cold water pipelines compared to a sharp 90° bend.
- Branch Connection
Equal Tee
Splits or combines flow in three equal-diameter directions. Standard in residential distribution manifolds, allowing a single supply riser to feed multiple zones.
- Branch Connection
Reducing Tee
Branches off a smaller-diameter outlet from a main run. Used when a primary supply line must feed a secondary branch of lower flow demand without a separate reducer.
- Inline Connection
Equal Coupling (Socket)
Joins two lengths of same-diameter PPR pipe in a straight run. The standard coupling for extending runs and repairing sections with a permanent heat-fusion bond.
- Inline Connection
Reducing Coupling
Transitions between two different pipe diameters in a straight line — used where a supply main steps down to a smaller distribution branch or point-of-use connection.
- Threaded Transition
Male Threaded Adapter (MTA)
Connects a PPR socket end to an externally threaded (BSP/NPT) metal fitting or valve. Enables integration of PPR systems with traditional metal plumbing components.
- Threaded Transition
Female Threaded Adapter (FTA)
Mates a PPR pipe to an internally threaded (BSP/NPT) metal component such as a tap, boiler connection, or pump inlet — completing the transition at terminal fixtures.
- Line Termination
End Cap
Permanently seals the open end of a PPR pipeline — used to pressure-test systems, cap off unused branches, or terminate dead-end sections of a distribution network.
- Dismantling Joint
Union
A three-piece demountable connector allowing pipework to be disconnected and reconnected without cutting — essential at pumps, meters, and serviceable equipment.
- Flow Control
PPR Ball Valve
Full-bore ball valve with PPR socket ends for inline isolation of zones and fixtures. Heat-fused directly into the pipeline for a leak-free shutoff point with zero corrosion risk.
- Distribution
Manifold Header
Multi-outlet distribution header for parallel supply of multiple zones from a single inlet — commonly used in underfloor heating, solar circuits, and high-rise riser distribution.
Available Sizes
20-160 mm socket thermal fusion type
200-250 mm butt fusion type
110-250mm electro fusion sockets
- System Performance
Why Are PPR Fittings the Right Choice for Hot and Cold Water Systems?
PPR fittings are precision-moulded polypropylene components designed for permanent, leak-free connections in water distribution networks. Heat fusion technology creates joints that are molecularly stronger than the pipe wall — eliminating leakage for life.
Corrosion-Free Operation
Resistant to mineral-rich municipal and borehole water supply — no rust, no scaling.
Stable Pressure Performance
Consistent performance under variable municipal and industrial supply conditions.
Safe Drinking Water Transport
NSF & WRAS certified with zero chemical leaching, independently verified.
High Temperature Resistance
Continuous rated service up to 95°C — ideal for solar heating and hot water.
- Product Specifications
What Are PPR Fittings, and Why Are They Important?
PPR fittings — including elbows, tees, reducers, couplings, and valves — are manufactured from virgin polypropylene for permanent, leak-free water systems. Fully compatible with PPR and PPRCT pipe systems, they are heat-fused to create joints stronger than the pipe itself.
Higher Pressure Ratings
Enhanced crystalline structure delivers improved pressure tolerance across sustained high-demand conditions.
Heat Fusion Jointing
Homogeneous molecular bond stronger than the pipe wall itself — permanently eliminates leakage risk.
Corrosion-Free Polypropylene
No rust, no scaling — reliable performance in mineral-rich municipal and borehole water systems.
Improved Thermal Resistance
Rated for continuous service up to 95°C — solar heaters, underfloor heating, and industrial hot water.
Complete Fitting Range
Elbows, tees, reducers, valves, and manifolds — fully compatible with standard PPR systems.
Low Noise & Vibration Performance
Polypropylene reduces noise and vibration, ensuring quieter piping in buildings
