Flared Ports for sale

These are available as one-piece ports made to order, or as single flared ends. Joiners and donut rings round out the range

The flares are made by heating PVC pipe and pushing onto a mold as detailed here

Currently all ports are light grey except the 86mm diameter, which are light green (recycled PVC)

If you're unsure what size you need, I suggest you review the Port Flares page

All prices are in Australian dollars $AUD

Sizes available

Pipe sizes

The sizes used are standard IPLEX PVC pipe, available from any plumbing supplier

Tolerances

Overall port length +/- 5mm for one-piece ports
Finished outside diameter of port flange +/- 3mm
It's always wise to wait till you recieve your ports before machining the opening in your enclosure

Postage

Postage within Australia is based on weight and volume. I've been advised that irregular shapes are based on weight alone, which is cheaper, so don't be surprised if the packaging is a funny shape!

• 1 metre of  86mm pipe weighs about 500gm
• 1 metre of 104mm pipe weighs about 1000gm
• 1 metre of 152mm pipe weighs about 2400gm
• 1 metre of 240mm pipe weighs about 5000gm
• Due to shortening of the pipe when flaring, add 30mm to the actual port length for each flare when estimating weight
  

• The 86mm donuts weigh about 175gm
• The 104mm donuts weigh about 200gm
• The 152mm donuts weigh about 300gm
  
  
• Packaging (bubble-wrap and cardboard) adds a bit more..
• Add about 600gm for small orders and 1.5kg for larger ones

Orders and Payment

Email me with your needs, including your postcode and I'll get back to you with a price which includes postage.

Payment can be by Postal note from Australia Post - will cost you about $4

I would expect to dispatch your order within 1 week from receipt of payment.

If you are not happy with the quality of the flares, return them and I'll refund your money, less the cost of postage.

Overseas Orders

I'm happy to supply overseas, but the postage can add up. A rough estimate is to add 50% to the cost of the ports.

For example a 1kg package Airmail to the UK costs $30.85 AUD or £11.87 UK.
The same package to the USA costs $24.70 Australian or $17.30 US dollars ..... prices & exchange rate 8th April 2007

For a package up to 2kg, this rises to $58.50 Australian or £22.50 UK
To the US it's $46.50 Australian or $32.57 US Dollars

You may also incur import duty and VAT depending on where you are, although for small packages, you're usually exempt.

The most recent shipment to the UK took 9 days.
The most recent shipment to the USA took 12 days.

Preferred method of payment is via a Bank Cheque in Australian dollars. NOTE: Your bank will charge you an additional fee to issue in Australian dollars. Alternatively, you can get the cheque drawn up in your local currency, however, it costs me $15 AUD to convert the cheque into Australian dollars at my end, so this needs to be added to your order. I also cop a long delay for the cheque to be cleared when it is not in Aussie dollars.

Supply of donuts alone is not recommended because local pipe sizes are going to be slightly different to those here. Obviously donuts plus flared ends or one piece ports are fine

The most popular ports for overseas are the 10 inchers.

Installation

PVC segments are best glued together with quick setting epoxy (5 minute Araldite). The ports need to be glued into position because there is not enough room for screws - epoxy or silcone can be used.

The donuts are finished with three coats of polyurethane to give a smooth surface. They're a pretty good fit, but due to variations in PVC thickness, you may need to give your joint a light sand and then wipe over with polyurethane.

Calculating required length

A flared port shares part of the air in the flare with the surrounding air, meaning that the port appears shorter.

The generally accepted adjustment is to subtract half the flare radius from the physical length to obtain the effective length. If both ends of the port are flared, the adjustment is done for each flare. See the Test Ports page for examples

Donut rings add 13mm to the effective length.

If your design is using any bends, measure the length through the centreline of the bends. Note that different brands of bends can have different lengths.

See the Sample arrangements page for some suggestions plus dimensions of the donut rings.
