Why does BRS recommend this?

For ultra-quiet plumbing a small section of silicone tubing is key. We recommend at least a small piece to isolate pumps from the ridged plumbing. Silicone tubing can kink fairly easily, so it isn’t the best to use in locations with hard bends, however by using a small piece in a straight section of plumbing can soak up almost all vibrations from return pumps and cut down on noise dramatically.


Four Sizes Available - Sold by the foot. Just enter how many feet you need, and we will send you a single piece that long. 

  • 3/8" ID - Works great for replacement air tubing on most protein skimmers.
  • 1/2" ID - Perfect for reactors, small return pumps, and other low flow equipment
  • 3/4" ID - One of the most common return pump plumbing sizes
  • 1.0" ID - Great for high flow return pump applications


High quality silicon tubing usually used between pumps and hard plumbing to help reduce vibration. Soft tubing will help dampen the vibration thus reducing the noise.

  • More resilient than natural rubber tubing
  • Popular choice for peristaltic pumps
  • Maintains flexibility over time
  • Use with barbed fittings



  • Temperature Range: -94° to 392° F
  • Tubing won't impart taste or odor
  • Use with water, air, and food and beverage.
  • Tubing is made from FDA-compliant resins. Material meets ASTM D2000. Tubing can be sterilized with steam (autoclaving) and radiation.
  • 1/16" Wall Thickness

Product Questions

Looking to use this tubing to connect my E-flux return pump to the Trigger Platinum 1'' fitting inside the sump, will the 1 in. tube fit that fitting or will I need to add a reducer.

Question by: JASON PHILLIPS on Nov 25, 2021, 6:11 PM
Hello The tubing is 1" Inner Diameter and will not fit the removable drain fittings. Thanks
Answer by: Christian Jimenez (BRS Staff) on Nov 28, 2021, 1:15 PM
What hose clamps do you recommend for use with the 1" ID soft silicone tubing?
Question by: Don bergman on Sep 11, 2020, 6:29 PM
We recommend zip ties for soft tubing.

Can this tubing be used for Apex DOS and DDR?
Question by: Michelle Smith on Jan 27, 2018, 10:38 AM
For the Neptune DOS and DDR you will want to use the DOS replacement tubing in the link below.

Is this platinum cured silicone tubing and what exactly is that?
Question by: Jim Madden on Oct 28, 2017, 11:35 PM

This is standard grade silicon tubing. It's likely that style of tubing you are asking about is intended for medical facilities and is probably a significantly higher cost. :-)

Can I use this from my overflow bulkheads to my sump? (Drain lines)
Question by: John on Feb 26, 2017, 12:58 AM
Hey there,
While the silicone hose is quite a bit more expensive than alternatives, if you wish to you, you certainly can use it for your drain lines.

Have a great day!

What diameter fis what barb? What tubing Inneed for a 3/4 inch barb? The 3/4?
Question by: Andres on Jan 18, 2017, 10:55 AM
Awesome question! For 3/4" barbed fittings, you will need 3/4" tubing. :-)
Answer by: Randy on Jan 19, 2017, 2:42 PM
Can this tubing (1" id) be used right off the return pump barb adapter to connect directly to the return overflow pipe instead of using vinyl? Can it handle 800-1000gph without bursting? I don't want clear tubing because of algae growth and the only vinyl tubing I can find in black with a 1" id is pond tubing and is not flexible at all. In fact, while trying to service my return pump, because the tubing is so rigid, it broke the seal on the bulkhead. I am looking for something more flexible to work with. My run goes right from the pump to the bulkhead piping from the overflow.
Question by: Jesse on Dec 4, 2016, 9:34 PM
Hey there! You can utilize silicone tubing directly on a barbed fitting, however I would recommend hose clamps to help secure the tube to the fitting while under pressure. :-)

Hello what is the OD of the 1/2 inch ID silicone tubing?
Question by: Anthony on Jul 25, 2016, 1:50 PM
Hi there,
The OD is just around 11/16” and the ID is exactly ½”.
Answer by: Charlie Onan on Jul 25, 2016, 2:35 PM
I have the 1/2 Mur-lok RO Inline Ball Valve Push Connect that come with the BRS deluxe GFO reactor, what size tubing goes into those. Is it the 3/4. Also I assume if you want 6ft you put 6 on the quantity as well.
Question by: Jeremy Bock on Apr 27, 2016, 11:41 PM
Great question!
Mur lok fittings will not work with Soft tubing. You will either need Polyethylene tubing (under RO tubing in the 1/2" size) If you prefer to use soft tubing it will be 1/2" and you can use a mur lok stem x barb adapter. Quantity 6 will receive one 6' tube.

I want to build a diy peristaltic pump. Would your hose work well for that?
Question by: Mike on Apr 21, 2016, 6:47 PM
Not really, You would need some type of surgical tubing which will last and be much more consistent and accurate.
Answer by: Connor on Apr 26, 2016, 4:28 PM
Hi I was wondering what the maximum psi capability would be for the tubing (1" is what i am purchasing) as well as the expected life expectancy and replacement cycle. Additionally what is the potential for tubing failure by breach (that could be bad!)
Question by: Robert on Apr 19, 2016, 11:08 PM
Great question!
Soft Tubing is not rated for much PSI (In the range of 10-30 PSI) These will last for years in the aquarium but 5 year replacement would be necessary. Additionally as long as used in aquarium applications the tubing will work great!

How long is a short piece of 1" id tubing ( in and out of an iwaki pump ) for vibration reduction?
Question by: Jim on Mar 8, 2016, 8:05 PM
Great question!
We find the longer segment of soft tubing the greater the reduction. Up to 6" of tubing can be used to help with keeping vibration down. Feel free to let us know if you have any further questions!

What is the correct size ratchet clip to use with the 1inch inside diameter silicone tubing?
Thanks in advance. Similar question submitted in the ratchet clamp section.
Question by: Jack S on Mar 7, 2016, 10:38 PM
Great question!
We use the 1" clamp with 1" silicone tubing. Pressing the end of the clamp together with pliers will be needed to make a complete connection. Feel free to let us know if you have any further questions!
Answer by: Connor on Mar 10, 2016, 2:00 PM
Can you provide the wall thickness of SKU: 207892 (3/4" ID) and SKU: 207891 (1/2 ID)
Question by: Daniel Etzel on Feb 10, 2016, 8:14 AM
Great question!
These will have 1/8" wall thickness on average. Feel free to let us know if you have any further questions!

White Soft Silicone Tubing. How does this tubing work for reef drain hose to the sump from an over the back CPR overflow box? Your assistance is greatly appreciated. Sincerely, Richard
Question by: Richard Nelms on Dec 27, 2013, 6:47 PM
Hi Richard,
It can be used where just about any flexible tubing would be used. Its benefit is largely that its really soft (which reduces vibration) so most folks just use a short length to connect to there pumps to reduce noise, though there is no reason you can't use it for longer runs.
Answer by: Bulk Reef Supply on Dec 27, 2013, 6:47 PM
How flexible is this hose? I would like to use it for water changes. Is it a suitable product for this purpose?

Question by: jim on Dec 20, 2013, 10:54 AM
Hey Jim,
The silicone tubing is super flexible, even more flexible then upbraided vinyl tubing and without being warmed up as well so I don't see any reason why you couldn't use silicone tubing for that.
