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 brass seal – Easy-to-connect coupling for compressed-air hoses
The Krause K+K hose coupling with a brass seal is designed for compressed-air hoses that are frequently connected or disconnected. The brass seal is used as the mating surface for a claw coupling with a rubber seal and prevents two elastomeric sealing surfaces from sticking together. This makes the coupling particularly easy to disconnect and reconnect.
The coupling is made of galvanized malleable cast iron and, in addition to the brass seal, features an oil-resistant hose ring and a galvanized retaining screw. A matching claw coupling with a rubber seal is used as the mating coupling. The maximum operating pressure is PN 10.
Benefits
✅ Ideal for frequent coupling and uncoupling
✅ Brass seal prevents two rubber seals from sticking together
✅ Robust galvanized malleable cast iron
✅ Oil-resistant hose ring
✅ Galvanized retaining screw
✅ Direct connection of compressed-air hoses
✅ Three hose sizes available
✅ Maximum PN 10

How It Works and Compatibility
✔ The brass seal is paired with a mating coupling featuring a rubber seal
✔ Prevents two elastomeric sealing surfaces from sticking together
✔ Particularly suitable for hose connections that are disconnected regularly
✔ Two couplings with brass seals are not the intended pairing
✔ The hose tail allows direct connection of the compressed-air hose
Installation Instructions
The hose coupling must be selected to match the hose nominal bore and installed using suitable hose fastening hardware. After installation, check that the hose is securely fitted and that the coupling connection is leak-free. If worn, the components of the brass sealing assembly can be replaced separately.
Applications
✔ Compressed-air hoses on compressors
✔ Pneumatic tools
✔ Workshops, industry, and construction sites
✔ Frequently changed hose connections
✔ Blasting technology within the permissible operating data
