  Product Description
These genuine replacement TPU bladders fit Kampa air tent models and provide an affordable fix when the internal inflatable tubes develop punctures or leaks. TPU (thermoplastic polyurethane) offers excellent durability and flexibility compared to older PVC bladders, maintaining pressure reliably across temperature changes. The bladders sit inside the outer fabric sleeves of your air frame system, working like bike inner tubes that you can remove, patch, or replace without needing specialist tools.

Replacing a Kampa air tent bladder takes around 15-20 minutes per tube. Deflate the beam completely, locate the zip on the outer sleeve, remove the old bladder, and slide the new one in with the valve positioned correctly. Re-zip the sleeve and inflate to the recommended PSI, checking for proper seating before full use.

Installing a replacement bladder extends your tent's working life by years rather than facing the expense of buying new tents or complete air beam assemblies. When stored properly between trips, quality TPU bladders maintain their integrity for 5-10 years of regular camping use. The outer fabric sleeves protect the bladders from UV damage and abrasion, so failures typically happen from accidental punctures, over-inflation, or valve issues rather than material degradation. Having spare bladders on hand means you're never stranded with a deflated tent, and many campers keep one in their repair kit alongside patches and valve tools.

Kampa designed their air frame systems with user serviceability in mind, making bladder replacement accessible for most owners without sending tents away for professional repairs. The zipped access points built into the sleeve construction let you reach the bladder quickly, and the TPU material accepts standard repair patches if you prefer fixing small holes instead of full replacement. Compatibility matters when ordering bladders, so check your specific tent model and year before purchasing, as Kampa updated their air beam designs across different product generations.

Frequently Asked Questions

What's the difference between the bladder and the sleeve in a Kampa air tent?
The bladder is the internal TPU tube that holds air pressure, similar to an inner tube in a bike tyre. The sleeve is the outer fabric casing sewn into the tent structure that protects the bladder from UV damage and abrasion. When you get a puncture, you're replacing the bladder only while keeping the existing sleeve intact.
How long do Kampa TPU bladders typically last?
Quality TPU bladders last 5-10 years with proper maintenance and storage. TPU material resists UV degradation better than older PVC designs and maintains flexibility across temperature changes. Failures typically result from accidental punctures, over-inflation beyond recommended PSI, or valve damage rather than material breakdown. Storing your tent dry and loosely folded in a cool location between trips maximises bladder lifespan.
Are Kampa bladders compatible with Dometic tents?
Dometic acquired Kampa in December 2018, and many current Dometic tent models use the same air frame technology originally developed by Kampa. Bladder compatibility depends on the specific model and production year, as both brands updated designs across different generations. Check your tent model number and year to confirm which bladders fit your air beam configuration before ordering.
Do I need to replace the entire air beam if one bladder fails?
No, you only need to replace the damaged bladder itself. Kampa designed their air frame systems with zipped access points that let you remove individual bladders from their outer sleeves without dismantling the tent structure. This serviceable design saves considerable expense compared to replacing complete air beam assemblies and takes 15-20 minutes per tube with basic tools.
Should I patch or replace a punctured Kampa bladder?
Small punctures under 5mm respond well to TPU repair patches applied following manufacturer instructions. Larger tears, valve damage, or bladders with multiple punctures warrant full replacement for long-term reliability. TPU accepts standard inflatable repair patches available in camping repair kits, but replacement bladders eliminate concerns about patch adhesion failing during trips in remote locations.
