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

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 DIN 3489 claw couplings and versions with safety holes

The NBR replacement gasket from Krause K+K is designed for standard claw couplings in accordance with DIN 3489, as well as for compatible couplings with holes for safety clips. It replaces worn, hardened, or damaged seals and ensures a reliable seal for the coupling connection.

NBR is used in the corresponding Krause K+K standard claw couplings for general compressed air applications. The corresponding coupling series are designed for a temperature range of −40 °C to +100 °C. Replacing the seals in a timely manner can prevent compressed air leaks, unnecessary energy consumption, and increasing leakage at the coupling point.

Benefits

✅ Compatible replacement gasket for Krause K+K claw couplings
✅ For standard DIN 3489 couplings
✅ Also for compatible couplings with safety holes
✅ NBR for general compressed air applications
✅ Quick replacement in case of wear or damage
✅ Cost-effective maintenance instead of replacing the entire coupling

Function and Compatibility

✔ Seals the coupling surfaces of the matching claw coupling system against each other
✔ Designed for Krause K+K standard claw couplings with NBR seals
✔ Can also be used for suitable lockable versions with drill holes
✔ Allows for the targeted replacement of the wear part without having to replace the entire coupling

Maintenance and Replacement

The seal should be checked regularly for cracks, hardening, deformation, and other signs of wear. Replacement is recommended if compressed air is escaping from the coupling connection or if the sealing ring is visibly damaged. Before installing the new seal, clean the seal seat and contact surfaces. The coupling should then be checked for proper fit and tightness.

Applications

✔ Maintenance of compressed air claw couplings
✔ Compressors and compressed-air lines
✔ Workshops, industry, and construction sites
✔ Blasting Technology
✔ Preventive maintenance of professional compressed air systems

FAQ

What material is the seal made of?
Made of NBR.

For which couplings is it intended?
For compatible Krause K+K claw couplings to DIN 3489, as well as compatible versions with safety holes.

When should the gasket be replaced?
In case of visible damage, hardening, deformation, or leaks.

Does the entire coupling have to be replaced to change a seal?
No. The seal is available as a separate wear part.

What is the SKU for the replacement gasket?
The item number is 008-02.

Conclusion

The Krause K+K NBR replacement gasket 008-02 is a small wear part that is essential for the reliable operation of the claw coupling system. Replacing it in a timely manner allows existing couplings to be maintained cost-effectively and prevents unnecessary compressed air losses.
