  • Perfect size

    This company is awesome. They send in great time and the 21' is perfect for my home. I honestly don't know anywhere else to buy the 21' Salter tubing. I hope they'll have it forever because I've been oxygen dependent for 17 years. Thanks.

  • Tough

    Like the length and toughness, but it does curl as I move around the house. The overall experience of shopping with you (my second time) is wonderful. On first order I needed a phone conversation with you and couldn't have had a better experience -- lovely and helpful lady. You have good products, decent prices, and fantastic staff.

  • It's pretty, but

    I haven't used it yet. It is replacing one on my portable travel machine and we won't be traveling for several months now.

  • Love these because they are crush proof.

    My company kept stepping on my old tubing setting off alarm on concentrater.

  • Green Oxygen Hose

    I really like this hose. I've tried others--they don't lay as flat. I also like the fact that they don't coil and tangle as easily as other hoses that I've tried.

  • Good Size

    21 feet with 7 foot cannula gets me everywhere I want to go in my apartment. Much better than regular hosing but does kink if you don't watch it.

  • It's NOT kink proof.

    As everyone else, we like the green can be seen better than the clear. We purchased a 35' hose. I know the longer the hose, the more it will tangle, but after 2 days, it was like wearing a garden hose. It twisted, it kinked, it basically got into knots. I can't help but wonder, if the hoses weren't thicker, if they would hold up better and tangle less.

  • I like the green tubing

    The green tubing is very easy to see at night so I don't trip on the tubing.

  • 21-foot green crush resistant multi-channel lumen oxygen supply tubing

    Super product, so much easier to use on my portable oxygen concentrator than ones supplied with the purchase of the portable concentrator my Dr. prescribed for me.

  • Works as touted

    I really like the green crush resistant tubing. I am pretty mobile around my house and frequently roll over the tubing with my walker, but no problem, it doesn't pinch off the oxygen flow. Attaching different lengths using swivel couplers works well, if you have the right swivel coupler, but that's on another review, :)

  • 21' tubing

    Love this tubing, does not kink up or twist like the clear tubing does. Reason I gave it a 4 star rating is, wish it came in 25'. This 21 is just a little short, 35' and 50' both are too long for my use. Tho I did just purchase the 4' cannulas. Think that will give me the little extra I need.
