The MRCOOL DIY Pre-Charged Line Set Extension Bundle offers the flexibility you need to extend your MRCOOL DIY HVAC system while maintaining high efficiency and performance. This kit includes a 16-foot and a 25-foot pre-charged line set, designed for use with 9K, 12K, and 18K DIY air handlers, whether wall-mounted or ceiling cassette.

Key Features:

16-Foot and 25-Foot Pre-Charged Line Sets

The bundle includes a 16-foot and a 25-foot pre-charged line set, both pre-filled with R-410A refrigerant, ensuring seamless connection and system performance. The pre-charged line sets eliminate the need for professional refrigerant charging, making installation straightforward and DIY-friendly.

  • Flexible Installation: The two different line set lengths provide flexibility, allowing you to navigate through tight or awkward spaces. Whether overcoming obstacles or needing extra length, these line sets are designed for more complex installations.
  • Pre-Charged with R-410A: Both line sets are pre-filled with environmentally friendly R-410A refrigerant, so there's no need for brazing, vacuuming, or refrigerant handling during the installation process.

Compatibility with Multiple Air Handlers

This extension bundle is compatible with 9K, 12K, and 18K MRCOOL DIY air handlers, whether wall-mounted or ceiling cassette models. This makes it a versatile solution for HVAC installations in various room sizes.

Effortless Connection with Couplers

The kit includes couplers to join the 16-foot and 25-foot line sets, extending the total line set length to 41 feet. This is particularly beneficial for MRCOOL DIY 4th Generation or EZPRO single-zone systems, where additional length is necessary.

  • Secure Fit: The couplers ensure a reliable, leak-free connection, maintaining the refrigerant flow between the line sets.
  • Quick Installation: The No-Vac Quick Connect design allows for a simple, fast connection without needing specialized tools or professional help.

75 Feet of Control Wire

Also included is 75 feet of control wire, ensuring that your indoor air handlers can effectively communicate with the outdoor condenser. This wire matches the total line set length, providing smooth system operation.

  • Efficient Communication: The control wire ensures that the air handler and condenser remain in sync, optimizing system performance.
  • Longer Reach: The 75-foot control wire complements the extended line set, making it suitable for larger installations or more complex setups.

Ideal for Tight Spaces or Long Installations

By combining the 16-foot and 25-foot line sets, this bundle allows you to extend the line set distance by 41 feet, ideal for installations where the outdoor condenser is farther away. The split length offers added flexibility when routing through basements, walls, or around obstacles.

Great replacement micro needling cartridges.
Picked today up for replacements for my Dr Pen micro needler. They arrived individually sealed, ready for use. They appear to be compatible good quality product just like my originals. Love the price point and savings. They fit my device perfectly. These arrived at the Dr Pen cartridge box although do not have Dr Pen brand on cartridges appear high-quality similar in packaging of the originals. They do not have the pen, cap safety guard, but that's really not a needed part of the product. Make sure to verify you have the right device. Be aware they do not fit correctly in M8 devices. Great value for the money you get 21 piece micro, needling cartridges, various needle styles. The kit comes with 36 needle, 12 needle and nano cartridges. I have already used the Nano cartridge and they are super comparable to original cartridges quality, They do not drag on the skin easily move and dispense face serum product. So far, I've been super happy with the replacements.

21 Piece Pen Cartridges
This 21 piece microneedling cartridge set is an excellent value and gives a lot of versatility for different skincare needs. I really like that it includes three different tip styles: nano, 12 pin, and 36 pin. There are 7 of each variety included, which makes it easy to customize treatments depending on what area I’m focusing on and how gentle or intensive I want the session to be. The cartridges fit my Dr Pen device well and feel securely attached during use. Everything came individually packaged and clean, which is important for at home microneedling routines. The nano tips are great for product infusion and glow-focused treatments, while the 12 and 36 pin options work well for more targeted skin texture care. Overall, this is a convenient and affordable replacement set that’s perfect for anyone wanting multiple cartridge options in one package.

Wish I Knew if it is Surgical Grade Steel
I have a Dr. Pen A6, and these non-OEM cartridges are a great value. You receive twenty-one cartridges in various sizes, and each cartridge is individually wrapped. These pins come in three sizes: thirty-six pin, twelve pin, and nano. I had no issue inserting the cartridge and locking it into place, and I didn't notice any wiggling or looseness. The pins were sharp and did not tear or drag on my skin. Of course, you will see small pinpricks where you have treated. One thing I would like to know is whether these are made with surgical grade steel. I would prefer that they are, but I don't see that information anywhere in the listing. That said, I didn't notice any unusual irritation. I now have a good variety of cartridges to be more consistent with my pen usage. I will update this review if I notice anything related to the steel used.

Perfect for Husbands but Wives may Enjoy Reading it Too!
For a long time I've wondered what my love language is in particular because they all sound good to me. I love receiving stuffed animals from my husband so maybe it is gifts. But then I also adore undivided attention when we watch movies nearly every night, so maybe it is quality time. When my husband empties the dishwasher that is good so maybe it is acts of service. Well how about a compliment, that is nice too. I think I'm greedy, I want it all. lol So don't think your wife will only like just one love language. Maybe she wants touch, quality time and acts of service too. This book explains what the typical differences are in what men and women want in regards to love languages. It also wisely explains how to apologize to a woman in a sincere way that will make her melt. It deals with anger and women want less of that! At the end of the book there are two tests, one for him, one for her. You can then figure out what each other's love languages are. As the books says, sometimes you are bilingual. Also there are various dialects. This book also makes you realize why sometimes the love language works and at other times it does not get the points you think you are getting. Like when a woman is really busy, some things mean more than others. While she's in the kitchen she might want help with the kids instead of touch or when she is feeling down she might want a compliment to make her feel appreciated. So I think learn all the love languages and use them wisely. I'm a fan! Any man who adds these languages to his skill set is going to be way more desired than usual. Women pay attention and this is a way of getting your point across. Oh and at the end of the chapters there is an easy "phrase book" so you get tips on specific things you can do to speak each language. I'm giving this book to my husband and I really hope he reads it! I'm also happy I read it because I've got myself more figured out. To my husband I say more love languages please!!!! ~The Rebecca Review
