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.

Hose clamp, Type B, with safety claws, DIN 20039, V4A stainless steel, PN 16, hose nominal bore 13–25 mm - 13/15 is in stock and will be shipped as soon as it is available again
Krause K+K Type B hose clamp DIN 20039 made of V4A stainless steel – with safety claws for corrosion-resistant hose assemblies
The Krause K+K Type B hose clamp according to DIN 20039 is designed for secure, mechanically robust hose assemblies. When used with compatible hose couplings, the integrated safety claws engage behind the safety collar, providing additional positive locking of the connection.
This version is made of V4A stainless steel / material 1.4401 / AISI 316 and is therefore particularly suitable for applications requiring increased corrosion resistance. The operating pressure is PN 16 according to DIN 20039. Three sizes are available for hose nominal bores 13/15, 19, and 25 mm.
Benefits
✅ Type B hose clamp according to DIN 20039
✅ Safety claws for couplings with a safety collar
✅ V4A stainless steel / 1.4401 / AISI 316
✅ High corrosion resistance
✅ Additional positive locking of the hose assembly
✅ Releasable screw connection
✅ Three common hose sizes available
✅ Operating pressure PN 16 according to DIN 20039

How It Works and Compatibility
✔ The clamp secures the hose after it has been pushed onto the hose tail
✔ With a compatible hose coupling, the safety claws engage behind the safety collar
✔ This provides positive locking in addition to the clamping force
✔ Particularly suitable for hose couplings with a safety collar
✔ V4A stainless steel offers a corrosion-resistant alternative to galvanized cast versions
Installation and Safety
The clamp must match the hose and coupling dimensions. With a coupling that has a safety collar, position the safety claws behind the collar. Tighten the screws evenly and alternately. Before commissioning, check the position of the safety claws, the secure fit of the hose, and the even clamping force.
Applications
✔ Compressed-air hoses
✔ Corrosion-prone industrial environments
✔ Mechanical and plant engineering
✔ Hose couplings with safety collars
✔ Applications with stainless-steel components
✔ Professional compressed-air and blasting technology
