Keep moisture loss to a minimum and protect the integrity of your laboratory and research applications with a flexible covering for test tubes, beakers, petri dishes and more.

Permeability Characteristics:

  • Oxygen (ASTM 1927-98): 150 cc/m2 d at 23°C and 50 RH

Great for. Recommend swapping set screws out for longer ones.
Works great and fits like a glove. Would recommend providing install instructions for less mechanically inclined individuals and definitely switching to MUCH longer set screws.

Perfect fit and great protection!
Color: Black, Size: 1
Just installed this SINGARO hitch cover on my truck and I'm really happy with it! The fit is absolutely perfect for my 2-inch receiver - slides in snugly with no wobbling or rattling while driving. The build quality feels solid and durable. The materials look like they'll hold up well against weather, road salt, and general wear and tear. Much better construction than the cheap plastic ones I've tried before that crack after a few months. Installation was super simple - literally just slide it in and secure. Takes about 10 seconds and gives your vehicle a much cleaner look from behind. No more exposed hitch receiver collecting dirt, debris, and moisture. What I really appreciate is how this keeps everything protected when I'm not towing. My old receiver was getting pretty rusty from being exposed to the elements, but this cover should prevent that problem going forward. The design looks clean and professional - not flashy but definitely an upgrade over having nothing there. For the price, it's a no-brainer accessory for any truck or SUV owner. If you've got a 2-inch hitch and want to protect it while improving your vehicle's appearance, this SINGARO cover does exactly what it's supposed to do. Simple, effective, and well-made!
