Coninx Gutter Internal Angle 90° uPVC Rainwater Fitting

Coninx Gutter Internal Angle

The Coninx Gutter Internal Angle provides a secure 90-degree directional change for rainwater systems inside roof perimeters. This uPVC component ensures a watertight transition at internal corners. It is engineered for compatibility with standard high-capacity gutter profiles used in residential and commercial construction.

Built for the Job

Plumbers and roofing contractors require reliable cornering solutions to prevent leaks at the most vulnerable points of a drainage system. This 90-degree corner piece handles high-volume runoff during heavy downpours. The internal radius design minimizes turbulence and prevents debris from snagging at the bend. It facilitates a smooth flow toward downpipes, reducing the risk of overflow during peak rainfall. Professionals rely on this fitting for its structural rigidity and long-term resistance to environmental stress.

• Connecting gutter runs at internal 90-degree roof junctions to maintain flow.

• Retrofitting existing rainwater systems to improve corner seal integrity.

• New build installations requiring UV-stabilized drainage components for durability.

Product Highlights

High-Grade uPVC Construction

The material resists corrosion and UV degradation in high-heat environments common on African job sites.

Integrated Seal Technology

• Pre-fitted rubber gaskets provide immediate compression seals upon installation.
• Advanced ribbing on the seals prevents slippage during thermal expansion cycles.

Technical Specifications

What’s Included

• 1 x 90-degree internal gutter corner fitting with pre-installed seals

On-Site & Workshop Notes

• Ensure the gutter ends are cut square and deburred before inserting them into the 90-degree connector.

• Apply a silicone-based lubricant to the rubber gaskets to ease the assembly of this fitting in cold weather.

• Install a support fascia bracket within 150mm of either side of the corner to manage the weight of water during storms.

• Align the expansion marks on the fitting to account for the movement of long plastic runs in direct sunlight.
