This airline tubing is made of high quality silicone and won't harden over time like other tubing will. This comes in 10 ft lengths and can be ordered longer with multiple quantities.
If using a sponge filter, this tubing is necessary to connect the air pump to the filter.
Due to shipping rates, shipping for this tubing is $2.00 for the first 10 foot of tubing and $1.00 for each additional 10 foot section. If purchased with other items, the shipping cost will be $1.00. Shipping will be added once you click "Pay with Paypal" which redirects you to Paypal's website, and your order can still be canceled.
