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 replacement gasket NBR – for claw couplings with locking nut, DIN 3238
The NBR replacement gasket from Krause K+K is designed for threaded claw couplings with a locking nut in accordance with DIN 3238. It allows for the targeted replacement of a worn, hardened, or damaged gasket, thereby ensuring reliable sealing of existing safety couplings without having to replace the entire coupling.
For the DIN 3238 series, Krause K+K uses oil-resistant NBR. The corresponding couplings have a 42 mm claw spacing with double safety cams and are designed for a temperature range of −40 °C to +100 °C and a maximum operating pressure of PN 16. Regular seal inspections are therefore an essential part of proper preventive maintenance for the coupling system.
Benefits
✅ Replacement gasket for threaded claw couplings DIN 3238
✅ Oil-resistant NBR
✅ Suitable for couplings with locking nuts
✅ Separately replaceable wear part
✅ Cost-effective maintenance instead of complete replacement
✅ Ensures a reliable seal at the coupling connection
✅ Useful for maintenance and preventive maintenance

✔ Oil-resistant NBR as the sealing material for the series
✔ Allows for the replacement of the wear part separately without having to replace the entire coupling
✔ Compatible with the safety coupling series featuring a 42 mm claw spacing
Maintenance and Replacement
The seal should be inspected regularly for cracks, hardening, deformation, and other damage. If there are leaks or visible wear, it is advisable to replace it. Before installing the new seal, clean the seal seat and contact surfaces. Afterward, check the coupling for proper fit, smooth operation, and leak-tightness.
Applications
✔ Maintenance of DIN 3238 safety couplings
✔ Compressors and compressed-air lines
✔ Industry and Construction Sites
✔ Mechanical and Plant Engineering
✔ Preventive Maintenance of Professional Compressed Air Systems
✔ Blasting technology within the permissible operating parameters of the coupling series
