Bellows U612-A 1.5″ — Stainless Steel Flexible Hose for Fuel Dispenser
U612-A — corrugated flexible hose (bellows) made from stainless steel SUS304, 1.5 inches in diameter, for the hydraulic block of a fuel dispenser. Used to connect components inside the fuel dispenser — pump, flow meter, solenoid valve — where a compensator for linear and thermal expansion is required. Working pressure up to 0.6 MPa (6 bar), temperature range −40…+80 °C.
Why a bellows is needed
- Thermal expansion compensation — in summer metal pipelines expand, in winter they contract. Without a bellows, stress develops at joints
- Pump vibration damping — reduces noise and wear on connections
- Installation simplification — compensates for minor misalignment of components
- Water hammer protection — absorbs sharp pressure spikes when the pump is switched on/off
- Repair without complete disassembly — flexibility provides access to adjacent components
Features
- Stainless steel SUS304 — resistant to corrosion from fuel, water, and aggressive additives
- Corrugated honeycomb structure — compensates for deformations up to 5–10% of length
- Working pressure 0.6 MPa — 2 times higher than the pressure in the fuel dispenser hydraulic block (3-fold safety margin)
- Temperature range −40…+80 °C — suitable for all climate zones
- Standard size 1.5″ — most common for Bennett-compatible fuel dispensers
Installation location
U612-A is installed inside the fuel dispenser hydraulic block between rigid components:
- Between pump and flow meter
- Between flow meter and solenoid valve
- Between valve and outlet to delivery hose
When replacement is needed
- Fuel leaks through corrugated bends — microcracks in bellows wall
- Cannot be compressed or stretched — corrosion, corrugation sticking
- Visible deformations or breaks after water hammer
- Scheduled replacement during major fuel dispenser overhaul (every 7–10 years)
Delivery and Warranty
U612-A is in stock. Shipment on the day of payment via Nova Poshta, SAT, or consolidated cargo throughout Ukraine (1–3 days). Manufacturer warranty 12 months. When ordering in bulk for a gas station network or as part of new fuel dispenser assembly — individual terms available. Technical consultation on selection and compatibility from an engineer within 1 business day. Export to Kazakhstan, Moldova, Georgia via NOVA GLOBAL.

SHIPPING INFORMATION FOR UKRAINE
Our company is committed to fast shipping and delivery throughout Ukraine. We work with carriers that offer the best balance of price and quality, including:
NOVA POSHTA
1-3 days. Delivery speed depends on your location. After placing your order and payment, we ship the same day or the next.
SAT
Delivery time 3-5 days. Speed depends on the distance between sender and recipient. This is the most economical option compared to Nova Poshta.
DELIVERY
Shipping takes 4-7 days. This is the slowest method, but its advantage is the low cost.
FREIGHT POOLING
Shipping is done via shared transport through a dispatcher. Finding a vehicle takes 1-2 days; speed depends on the destination (major cities are faster, remote villages slower). This method is cheaper than the carriers listed above.
We work throughout Ukraine, and on request can arrange delivery via another courier service not on our list.
After placing your order in our online store, please provide the following information for delivery to your region:
- Recipient's full name
- City or town
- Number of the nearest warehouse (if shipping via courier services)
- Mobile phone number
Once the goods are shipped, we will provide you with the waybill number. When picking up your order, please bring your passport and the waybill number.
NOTES:
- The seller is not responsible for the operation of postal / courier services.
- Shipments are insured for full value; in case of damage the carrier is obligated to compensate you in full.
- Shipping costs are paid by the buyer (or by mutual agreement).
- If the requested product cannot be supplied, an equivalent replacement will be offered upon your approval.
If you couldn't find an answer to your question in this section, please contact us for more detailed information.
PAYMENT METHODS
After placing an order for a selected product in our store, we verify stock availability and confirm with you. Payment can then be made using one of the following methods:
- Bank transfer to the company account (VAT included).
- Cash on delivery (payment upon receipt).
Before paying via bank transfer, please contact us to confirm product availability.
Cash on delivery is processed at the carrier's warehouse. The service fee is 2% of the total + 15 UAH for payment processing. For an order of 1000 UAH you will pay 35 UAH for this service plus the shipping cost.
The second method is more reliable as you can inspect the goods on the spot, but it is also more expensive, so before paying you may want to consider which method suits you best.
If payment is received by 12:00, we ship the same day; if payment arrives later, shipping is processed the next day.
For any questions about payment, please contact us — if you haven't found an answer to your question, we will provide more detailed information.
