Deadline for 7/4/2024

Monday, June 10th is the last day we are taking rack and tube orders and having them delivered before 7/4/24. Any order received after 11:00pm on 6/10/24 is unlikely to arrive prior to 7/4/24. This applies to all racks and tubes.


  1. Why use HDPE and not PVC?
    HDPE is made from the same material as what you typically see in a shampoo bottle (take a look at the bottom next time you shower, see HDPE?). It's plyable, yet strong. Also alot of milk jugs are made out of HDPE, but that's pretty thin. PVC is brittle. If you have a blowout or flower pot (basically a shell that breaks in the motar tube) then you need a mortar tube that can absorb the pressure (HDPE). PVC will have a pipe bomb effect and you don't want to get that junk in your body! HDPE tubes will expand and tear rather than shatter. Whatever you do, don't use PVC! PVC is often used for rocket racks... and that's OK because the actual firework is not inside the PVC, only the stick goes into the PVC.

  2. Can I pick up my order locally (we are located near Loveland, Ohio)?
    Yes. Please send us a message and we will make it happen. Local pickups are by appointment.

  3. Can you ship an order to my state?
    We ship to any of the 50 states! That means we can ship to New York, California, Hawaii, Alaska, etc. If it's part of the 50 states in the USA, we will ship to you. Currently we don't ship internationally. Hawaii and Alaska orders will probably ship USPS.

  4. Can I combine my order if I missed something on my first order?
    Yes and No! We are very busy in May, June and December. If you want to add to your order in any of these months we cannot accommodate this request. You will need to place a second order. It's very difficult to manually manage these requests in the busy times of year. No matter what time of year it is and you want to buy more items you will need place another order. In the event it's not May, June or December then please contact us immediately after your second order and tell us to combine your order. Please include the order numbers!

  5. What is the inner diameter (ID) and outer diameter of a DR11 and DR9 consumer mortars?
    The ID of a DR11 mortar tube is 1.91" and the OD is 2.4" A DR9 tube has a thicker wall and it has an ID of 1.81", but the OD is the same as DR11, which is 2.4 inches.

  6. What is the difference between a DR11 tube and a DR9 tube and which one is better?
    DR11 has an ID of 1.91" and DR9 is 1.81 inches. DR11 is the most common tube, and it's our best seller. If you don't know, buy DR11. Why DR9 then? DR9 is used for smaller shells. Yes, many fireworks shells fit into a DR9 mortar, but there no guarantee that your shells (mine shells too) will fit into the mortar. Again, when in doubt, go with DR11.

  7. Will my 1.75" shells work in PYROBOOM mortars?
    Yes. All consumer firework shells will work in our mortars. Make sure you purchase 12" DR11 mortars if you don't know which type to buy.

  8. What is a mine shell and 8" mine tubes for?
    A mine shell is a shell that breaks right from the tube shooting stars from the ground up. They also have a great low ground boom, which is very cool. To get a wider spread of the stars we made 8" mortars just for you! They are cheaper too. Remember, use only 8" mortars for mine shells. Never for aerial shells. (They break in the sky). Yes, of course, you can shoot mine shells from a 12" tube.

  9. Why do most your racks have a common factor of 6 (6, 12, 18, 36)?
    Nearly all mortar shell kits you buy at the store come in packs of 6 or 12. We try to match those shell kits by making our racks that match what you buy.

  10. How long will a HDPE PYROBOOM consumer firework mortar tube last?
    HDPE mortars should last your lifetime. The plug probably won't make it that long. It's highly recommended that you inspect your empty mortars once a year. Look at the entire tube and take a good look at the plug. Make sure it is not loose. If it is, replace it! Keep your mortars clean by blowing them out with compressed air before your next show. Also common sense goes a long way. It’s not a good idea to keep your mortars outside if you live in Michigan's upper peninsula. Keep those tubes inside where it's dry, just like your fireworks.

  11. When does my order ship?
    PYROBOOM is open all-year round. We keep stock all year round too. Typically your order will ship within 48 hours. It also depends on the size of your order (if you order 748 tubes it might take a day longer). We use FedEx as our primary carrier and you'll receive a tracking number from them via email once your order ships. Of course, if we are super-busy (June), then it will probably take longer to get your pyro goods.

  12. You have great prices, but shipping, c'mon help me out here?
    You ain't kidding! Shipping is a killer. We do get a discount from FedEx, but each consumer tube nearly weighs a pound. So 50 mortars is about 40 pounds. We can't do anything about shipping. We are at the mercy of the carrier. FedEx is pretty amazing actually and you get tracking info. The drivers that come and pick up your stuff are really awesome and we have great time when they come (they seem to like us, which is a good thing). Did you know that if you live in Ohio (except the very upper east), Indiana, Kentucky, West PA, lower (like below Lansing), Chicago land and the Memphis, TN area you will get your stuff in 1-day after it ships! The rest of lower 48 states is mostly 2 to 4 days! See our shipping map here.

  13. What's the difference between 12" and 15" DR11?
    Sarcastic answer: 3 inches! Some like to use 15" because their shells have a longer leader fuse (Excals), but it's not a solid reason to buy the 15 inch. It's used for mult-break shells too (like 4 or more, but the 12" still should be fine). There are rumors that the 15" tube will make the shell go higher, but this has never been proven. If it does go higher, I'm thinking it's only like 10 feet. Nothing to write home about. Personally, I only use the 12" mortar tube. Oh yeah, I like shells!
