PVC External Low Reduction 160×110 AQUER DK117

AQUER PVC external low reduction 160×110 (model DK117) is a rigid PVC pipe fitting designed to join a 160 mm external drain or ventilation pipe to a 110 mm outlet. Intended for outdoor installation, the fitting provides a compact low-profile transition that maintains flow direction while reducing diameter. Its corrosion-resistant PVC construction makes it suitable for use in roof drainage, gutter systems and external plumbing where a reduced outlet is required.

Advantages

The AQUER external low reduction delivers a consistent, secure diameter transition with minimal protrusion from the pipe run. Made from durable PVC, it resists corrosion and weathering typical of external installations. Its molded geometry ensures alignment between the 160 mm inlet and 110 mm outlet, facilitating reliable connections with compatible sockets and seals. The compact design helps keep roofline and wall-mounted drainage solutions neat and accessible for inspection and maintenance.

Suitable for

• Roof and eaves drainage systems requiring a reduced outlet
• Gutter downpipe transitions from 160 mm to 110 mm
• External ventilation duct runs where a smaller outlet is needed
• Repair or modification of existing outdoor PVC drainage installations

Key specifications

• Material: rigid PVC (polyvinyl chloride) suitable for external use
• Connection sizes: 160 mm inlet to 110 mm outlet
• Type: external low reduction fitting with compact profile
• Application environment: outdoor drainage and ventilation systems
• Resistance: corrosion and weather-resistant under normal external conditions

How to use

Before installation, confirm compatibility with existing pipe sockets and any required seals or adhesive systems for external PVC. Clean mating surfaces and ensure pipes are cut square. Insert the 160 mm inlet onto the upstream pipe and connect the 110 mm outlet to the downstream pipe or socket, using appropriate PVC solvent cement or rubber seals where specified by local installation practice. Ensure correct alignment and slope for drainage; tighten or secure as needed and check joints for leaks after the first water flow.

Usage recommendations

Use in accordance with local building codes and manufacturer guidance for outdoor PVC fittings. Avoid exposure to direct sources of high heat or mechanical stress. For long-term performance, inspect joints periodically for signs of wear, UV degradation or movement, and replace seals or fittings if leakage or damage is observed.
