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.

Stainless steel hose coupling with FKM/FPM fluoroelastomer seal and safety collar, DIN 3489, max. PN 16, hose nominal bore 13–25 mm - 13 is in stock and will be shipped as soon as it is available again
Krause K+K stainless-steel hose coupling DIN 3489 – V4A with FKM/FPM seal and safety collar
The Krause K+K stainless-steel hose coupling combines the proven 42-mm claw coupling system with high corrosion resistance and a hose connection that can be additionally secured. It is designed for professional compressed-air applications requiring both durable materials and mechanically robust hose fastening.
The coupling body is made of V4A stainless steel / material 1.4401 / AISI 316 and is fitted with an FKM/FPM fluoroelastomer seal. All available versions feature a safety collar. This is intended for use with a suitable Type B hose clamp, whose safety claws can engage behind the collar. The claw spacing is 42 mm and the maximum operating pressure is PN 16.
Benefits
✅ V4A stainless steel / 1.4401 / AISI 316
✅ FKM/FPM fluoroelastomer seal
✅ 42 mm claw spacing
✅ All versions with safety collar
✅ Additional positive locking of the hose assembly possible with a matching Type B clamp
✅ High corrosion resistance
✅ Three common hose sizes available
✅ Maximum operating pressure PN 16

How It Works and Compatibility
✔ Symmetrical claw coupling head with 42 mm claw spacing
✔ The safety collar allows additional positive locking of the hose assembly
✔ A suitable Type B clamp can engage behind the collar with its safety claws
✔ The hose tail connects directly to the compressed-air hose
✔ FKM/FPM seal and V4A stainless steel are intended for demanding environments
Installation and Safety
The hose size and hose clamp must match the coupling and the actual hose outer diameter. With the intended Type B clamp, the safety claws are positioned behind the safety collar. Tighten the clamp evenly, then check the hose fit, position of the safety claws, and tightness of the connection.
Applications
✔ Chemical and petrochemical industry
✔ Corrosion-prone compressed-air systems
✔ Mechanical and plant engineering
✔ Compressed-air hoses with increased hose-securing requirements
✔ Professional industrial and process applications within the permissible operating data
