The Easywell Bowed Expansion Tank Bracket Series is purpose-built for wet, humid, and corrosive environments, ensuring long-lasting support for thermal and water-heater expansion tanks.
Unlike flat supports, the bowed frame design evenly distributes load stress while preventing water accumulation — making it the ideal choice for bathrooms, coastal buildings, industrial laundries, and compact mechanical rooms.
Engineered with stainless-steel or epoxy-coated carbon steel, each bracket offers superior resistance to humidity, salt air, and chemical exposure, ensuring your hydronic system stays safe and reliable for years.
Designed with epoxy or stainless finishes that protect against rust, steam, and salt exposure. Perfect for bathrooms, coastal homes, and marine applications.
Each bracket includes sealed joints and precision-threaded ports that eliminate vapor ingress — maintaining performance under high humidity (RH ≥ 85%).
The bowed frame evenly distributes load pressure, protecting both wall and piping. Suitable for tanks up to 25 L / 50 kg depending on model.
Slim vertical profile fits into small boiler cabinets or under-ceiling spaces where installation depth is limited.
Standard ¾″ M / ½″ F / ¼″ Gauge threaded ports make connection simple, while pre-drilled wall plates reduce setup time.

The Steel D42 Bowed Expansion Tank Bracket features a 250 mm total length with a curved outlet radius of 100 mm, providing optimal balance and structural strength for small to mid-size expansion tanks.
The wall plate measures 110 mm × 55 mm × 3 mm, equipped with slotted holes for vertical installation.
It includes three ½″ threaded connection ports and a ¾″ outlet for expansion tank mounting, enabling seamless integration into heating systems.
The 60 mm and 80 mm spacing between ports simplifies valve, air vent, or gauge assembly.
Steel D42 Bowed Expansion Tank Bracket — 250 mm length, ¾″ outlet, ½″ auxiliary ports, and 110 × 55 mm wall plate for stable wall installation. Ideal for compact heating systems and residential hydronic setups.

The Heavy-Duty Bowed Expansion Tank Bracket is built with an extra-thick 3 mm wall plate (70 × 90 mm) and a 255 mm total arm length, ensuring high mechanical resistance for heavy expansion tanks in industrial settings.
It features four threaded connection points — ¾″ inlet/outlet, ½″ auxiliary port, ⅜″ valve port, and ¼″ gauge port — all aligned along a 175 mm center spacing.
The reinforced curved elbow minimizes stress on the pipe junction, while the 3 mm wall thickness supports working pressures up to 10 bar.
Heavy-Duty Industrial Bowed Expansion Tank Bracket — 255 mm frame with multi-port ¾″, ½″, ⅜″, and ¼″ connections. 3 mm wall thickness and 10 bar rating for industrial boiler and heat system use.

The Space-Saving Bowed Expansion Tank Bracket has a 271 mm total length and 106 mm vertical height, using a Ø32 × 1.5 mm pipe for lightweight yet stable support.
It integrates multiple connection points: ¾″ male outlet, ½″ female safety-valve port, and ¼″ gauge port, spaced 43 mm – 69 mm – 65 mm apart for precise modular assembly.
The wall plate thickness (approx. 3 mm) and 43 mm mounting offset allow stable wall installation even in narrow mechanical cabinets.
Space-Saving Bowed Expansion Tank Bracket — Compact 271 × 106 mm design with Ø32 × 1.5 mm pipe and precision-spaced ports for gauge, valve, and air vent. Engineered for modern hydronic and heat-pump systems.
