Overview

The DEKS SS Gibault DGB450BL is designed to connect and repair pressurised pipelines such as water supply lines, irrigation systems, and industrial applications, and is suitable for DN450 pipes with an outside diameter of 488–512mm. Compared with shear banded couplings or standard pipe joiners, the Gibault coupling is constructed with a 316 stainless steel barrel with ductile iron end rings tightened by stainless steel bolts, making it suitable for pipeline systems with working pressures up to 16 bar.

The DEKS Gibault designs allow for connection with all types of pipe materials including ductile iron (DI), asbestos cement (AC), cast iron (CI), PVC, or steel pipes in pressure rated applications.

 The EPDM rubber gasket located on top of the stainless steel barrel forms a water tight seal when tightened and allows for angular deflection to accommodate minor pipeline movement due to vibration, ground settlement, or surface loading. The product is WSAA approved for use in Australia and complies with the requirements of modern pressurised pipeline systems.

Great quality chair, regardless of price.
Color: Black+white, Size: Pack of 1, Color: Black+white, Size: Pack of 1
Great quality chair, regardless of the price, period. So well packaged that it took almost as long to unwrap as assemble. Assembly was easy (loved the Allen wrench with sturdy handle). I am 6'2" and the fit and height adjustments work well for my height. Comfort is personal, so I like the semi-firmness of the seat. While the chair is constructed of heavy gauge plastic the base is solid metal with enamel finish: I love the look. The arm rests line up perfectly to my computer keyboard. I expect many, many years of service.

Great Value for a Comfortable Home Office Chair
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
I’ve been using this chair for a couple of days now, and honestly, it’s been a solid upgrade from my old one. I work from home most days, so comfort matters a lot—and this chair delivers better than I expected for the price. The first thing I noticed was the lumbar support. It’s actually adjustable and makes a noticeable difference, especially if you tend to sit for long stretches. My lower back used to get sore after a few hours, but that hasn’t really been an issue since switching to this chair. The mesh back is also a nice touch—it keeps things breathable, which I didn’t think I’d care about until I had it. Assembly was pretty straightforward. Took me maybe 20–25 minutes without any frustration. Everything lined up well, and the instructions were clear enough. In terms of comfort, the seat is firm but not hard. It doesn’t feel like one of those super plush chairs, but I actually prefer that because it feels more supportive over time. The reclining feature is smooth, and I like that you can lean back a bit when you need a break. Overall, I’d say this is a great value for a home office setup. If you want something ergonomic and comfortable without spending a fortune, this chair is definitely worth considering.

Excellent Office Chair
Color: Black+white, Size: Pack of 1
I just received my TRALT Office Chair. First of all, I was impressed with the packaging of this item. When I opened the box each piece of the chair was wrapped in plastic or bubble wrap. Everything in the box arrived safely and without damage. Secondly, the instructions to assemble the chair were very each to follow. I was impressed with the Allen wrench which had a handle attached to it. This made screwing in the screws very easy. I was able to assemble the chair without any difficulty. Lastly, the look of the chair and the comfort is exceptional. I ordered the black/white chair which looks amazing. The comfort of the chair is really excellent. My back is supported by the lumbar seat and having the armrests being able to go up when not needed is wonderful. The quality of the chair is definitely worth the price.

a good choice
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
Assembled chair only to find that the lift cylinder was faulty. Would have preferred to be able to just get a replacement cylinder but calling China didn't seem like a viable option. Guessing which one & buying it online would involve paying for a good portion of what the chair cost. Customer service could only offer a replacement or refund. We're disassembling (so much fun?!) to send it back. The chair itself was very comfortable, assembled fairly easily and instructions pretty clear. Again, if we could only have asked the seller for the replacement part......**Update**...Or if the instructions that seemed so clear were clearer!, as we started to disassemble, we decided to see what would happen if the tension knob (see photo) was loosened. IT ALLOWED THE LIFT CYLINDER TO WORK. Not at all what the instructions say. At any rate, we're keeping the chair.

This chair is amazing
Color: Sky Blue, Size: Pack of 1, Color: Sky Blue, Size: Pack of 1
⭐⭐⭐⭐⭐ Absolutely love this chair! It was super easy to assemble—I had it set up in no time with clear instructions and minimal effort. The comfort level is fantastic; the seat cushion is just right and the back support makes it great for longer sitting sessions. The color is beautiful in person—clean, modern, and adds a fresh pop to the room without being overwhelming. I also really like the smooth wheels and sturdy build; it feels stable and well-made. Overall, this is a great combination of style, comfort, and value. Highly recommend!
