Leasing & Rent-to-Own
Leasing & Rent-to-Own
We offer leasing and rent-to-own financing options exclusively to business owners, tradespeople, and the self-employed for selected products with a net merchandise value of €1,000 or more. Below you will find the key differences between these two financing options.
Leasing
In a lease, the product is made available to the lessee for use in exchange for regular lease payments. The lessor is responsible for accounting for the lease. The lease payments can generally be claimed as business expenses for tax purposes. These are gross payments, and value-added tax is charged throughout the entire term. At the end of the agreed-upon basic lease term, it is generally possible to purchase the product.
Hire Purchase
Hire purchase is economically equivalent to installment purchase. The product is capitalized on the hire purchaser’s balance sheet and depreciated in accordance with the official depreciation tables. Upon payment of the final hire purchase installment, ownership of the item is transferred to the hire purchaser. Value-added tax must be paid in full with the first hire purchase installment (transitory item).
Shipping & Delivery
Shipping & Delivery
Depending on the size, weight, and nature of our goods, they are shipped either via parcel service or freight carrier. We select the shipping method at our reasonable discretion.
The delivery times listed in the online store are non-binding estimates, unless a binding delivery date has been expressly confirmed in writing. They are based on the information available from our manufacturers, suppliers, and logistics partners at the time the order is placed.
Most of the products offered are shipped directly from the manufacturer or from external central warehouses (direct shipping). As a result, delivery times may differ from the estimated times provided. Delivery delays may occur, particularly in the event of material shortages, production delays, supply bottlenecks, force majeure, or other circumstances beyond our control.
Disclaimer:
We assume no liability for delivery delays resulting from circumstances beyond our control. This applies in particular to delays caused by manufacturers, suppliers, shipping companies, or other third parties. Liability for any resulting damages—in particular for indirect damages, consequential damages, or lost profits—is excluded to the extent permitted by law.
Partial deliveries are permitted, provided they are reasonable for the customer. This does not result in additional shipping costs, unless otherwise agreed.
The exact delivery time for an item can be provided on an individual basis upon request, either before or after the order is placed.
Please contact us by phone at +49 (0)2551 5030 or by email at shipping@strahltechnik-express.de.
In the event of significant delivery delays, we will inform the customer immediately. The customer’s mandatory statutory rights remain unaffected by this.

Krause K+K hose coupling with safety holes and safety collar – for particularly secure compressed-air hose connections
The Krause K+K hose coupling with safety holes combines two safety features: additional holes for safety clips in the coupling head and a safety collar for a mechanically secure hose assembly. This version is therefore particularly suitable for demanding compressed-air applications where both the coupling connection and the hose fastening require additional security.
The coupling is made of galvanized malleable cast iron, has a 42 mm claw spacing, and is equipped with an NBR rubber seal. The temperature range is −40 °C to +100 °C, and the maximum operating pressure is PN 10. All versions offered in the store feature a safety collar.

✅ Safety holes for additional locking clips
✅ Safety collar for positive locking of the hose assembly
✅ 42 mm claw spacing
✅ Galvanized malleable cast iron
✅ NBR rubber seal
✅ Temperature range −40 °C to +100 °C

How It Works and Compatibility
✔ Safety holes in the coupling head allow additional securing with suitable locking clips
✔ The safety collar, used with a matching Type B hose clamp, provides additional positive locking of the hose assembly
✔ 42-mm coupling head within the corresponding safety-coupling series
✔ Direct connection to compressed-air hoses via the hose tail
✔ Two different safety principles can be combined in one connection
Installation and Safety
Use a hose clamp that matches the hose dimensions. For versions with a safety collar, a suitable Type B clamp is recommended, with its safety claws positioned behind the collar. After coupling, suitable locking clips can additionally be inserted through the safety holes. Before commissioning, check the coupling, hose fastening, and safety elements for a secure fit.
Applications
✔ Mining and tunnelling
✔ Industry and construction sites
✔ Compressed-air hose lines with increased safety requirements
✔ Compressor systems
✔ Blasting technology and other professional compressed-air applications
