O-ring bead forming tool for aluminum hard lines

Post by bond007 »

This is one of a few questions (putting into separate threads) on my custom HVAC project.

Is there a "hand" tool (as opposed to an industrial end-form machine) that can put an o-ring bead on aluminum tubing? I would like to retain OE engineering of having hard lines except for the lines to/from the compressor having rubber.

After too many hours of research, all I've found is the Mastercool #72485 3/8" push-connect which might work for a #6 but doesn't deal with the #8 or #10 lines.

I don't know of any tools for the purpose of which you speak. But an alternative is to obtain whatever size aluminum tubing you need, purchase an already formed o-ring fitting in the same size and material, swage each end of the tubing and fitting (so that one fits inside the other), and aluminum-braze the two together. Swaging tools can be had for reasonable prices.

The cheapest way to do it, or braze connections.

Styling T-Shirts: All the Do’s and Do Not’s You Must Know

T-shirts represent the ultimate wardrobe staple worth styling in fresh ways. You can wear them anywhere, from gym to cafes to dates. Yet elevating basic tees into enviable outfits requires awareness of fit, proportion and composition. Certain styling techniques polish casual tees into high fashion looks, while other approaches falter into sloppiness. Mastering the nuances of t-shirt styling unlocks their full fashion potential.

Follow this LionKingShirt guide of do’s and don’ts, to always look fabulous in your favorite tees!

T-Shirt Style Tips: How to Look Incredible in Tees

When styling a T-shirt, first seek out the most flattering fit and fabrics that drape beautifully on your frame. Look for soft, lightweight tees in materials like cotton, modal, or silky polyester blends that contour curves without clinging too tightly. Scoop necks, V-necks, and crew necks all complement different body types. Cropped and cap sleeves stylishly show hints of skin.

Next, build outfits that accentuate your best assets. High-waisted bottoms like jeans, skirts, and shorts cinch the waist elegantly while showing some leg. Tailored blazers, moto jackets, and slim cardigans lend structure. Tuck tees into skirts or pants to accentuate your waistline. Half-tuck into jeans for a relaxed vibe. Knot shirts at the waist for a fun touch. Monochromatic top and bottom pairings give a streamlined, elongating look.

Take your tee from basic to bold with the right accessories. Statement necklaces, chokers, and delicate chains dress up necklines. Dainty bracelets and stacked bangles adorn wrists. Bold belts cinch the waist. Stylish shoes range from sneakers to strappy heels. A sleek handbag or colorful clutch amps up the outfit.

You can also play with proportion by going oversized on either your top or bottom half. An oversized slouchy tee flows beautifully over leggings or tight jeans. A fitted tee can be tucked into billowy, wide leg pants. Experiment with unexpected pairings.

When shopping, look for vintage band tees, graphic tees with cool artsy prints, pocket tees, baseball tees, and fitted crew necks that you can dress up or down. Well-fitting solid color tees in versatile white, black, grey, and nude hues give you a blank canvas for creative styling.

T-Shirt Style Mistakes: How to Avoid Looking Sloppy

When styling Lion King T Shirts, there are some definite fashion faux pas to avoid at all costs. Don’t select shirts made of flimsy fabrics that lose their shape and cling to your body unflatteringly. Pass on tees that are excessively oversized, hiding your figure under billowing fabric. Steer clear of deep or oversized armholes that show too much underarm area. Ill-fitting tees simply look messy.

Be cautious of pairing tees with bottoms that hit at the widest part of your hips, losing any definition to your waistline. Low rise pants or shorts should be avoided as they can reveal too much midriff when paired with the wrong top. Distressed cutoff jean shorts and ragged jeans appear more messy than fashionable. Be wary of matching loose, baggy tops with flowy bottoms which hide your shape under fabric.

Go easy on bold graphic prints, cluttered designs, and wild patterns which compete for attention rather than complement. Novelty tees with corny phrases more often flop than look hip. Don’t over-accessorize with competing jewelry and accessories that appear discombobulated. Less is more when accessorizing tees.

According to Marc Katz, an expert in POD T-shirts as well as fashion, you should avoid dressing oversized tees with skin-tight leggings, overly cropped shirts with low-rise pants, mixing baggy tops and bottoms, pairing a form-fitting tee with voluminous pants. Even wearing casual tees with formal satin or sequined fabrics is a no-no, because their vibes will clash.

When evaluating your t-shirt selection, consider phasing out old shirts with holes, stains, and frayed hems that have passed their prime. Unflattering tees will portray more laziness than style. Following these guidelines helps you avoid sloppy style mistakes and always look fashionably put-together in your favorite tees!

Wrapping Things Up

T-shirts can be styled for nearly any occasion from workouts to nights out by keeping fit, function and aesthetics in mind. Choose high-quality tees in soft fabrics that flatter your shape. Pair with bottoms that show off assets and complement proportions. Use accessories strategically without overdoing it. Avoid unflattering silhouettes, mismatched pieces, and cheap fabrics prone to static cling. With some practice identifying optimal styles, fits and pairings, you’ll be able to elevate your tee collection into envy-worthy looks.

I have a smaller bead roller to be able to put a bead on larger aluminum tubing for my aluminum intercooler and radiator pipes. The die won’t fit a #8 and would probably barely fit a #10.

If this isn’t what you are referring to, can you reply with a manufacturer and part number (did some searching already and best I can tell is what you are talking about is what I already have)?

You will need to be triggered by someone else, as I did not remove the link! I get triggered by certain people as well. :lol:

I don't think a single image of a tool would have been removed; certain links, yes. People can Google shop on their own time and platform! I think we have told you this many times. Repeatedly asking will not change the outcome of the response. If you feel this restriction voids the information you glean from the site, I think as vast as the internet is, someone has to have a site that fits in better with your feelings of how it should be run.

PS: There is no need to run me down in a post. You have already done that in the past. And since I'm recovering from spine surgery. My delete finger is less tolerable.

I did see the link. I'm not sure it will seal well with that short of a nipple. I still think your best option is welding a section of fitting on the aluminum tubing. This is how it's been done for as long as I can remember.
