Looking for the little red plastic shrouds used on e-matches

[KevinT]

Does anyone know where to buy the little red plastic shrouds that are used to cover the e-match on igniters? I did a quick search on google and could not find anything.

These red shrouds.



Thank you,

You can accomplish the same thing by wrapping a cone of masking tape on the wire and igniter.

Not sure if this is what you are looking for. Looks like they have some related products.

You can dig them out of my garbage can for free. I throw away 10 to 20 prepping for a launch.
Send me your address and I will mail them to you.

Sent my address. Thank you

The reason I need these is I'm trying out the Tinder Rocketry CO2 ejection system with Arc Technologies electronic e-matches. The little red shoulds are needed for the well.

Thanks again

I would "guess" they are SC Series Caplugs, (or equeal). Here is table with all the standard sizes.
https://www.caplugs.com/sleeve-caps-scI don't have any with me to look at closely right now.

Finding a distributor who breaks up the OEM packs onto smaller volumes, will be your next issue.

I think this is probably what you're looking for... MJG Firewire Initiator.

You could email MJG and see if they would sell you some.

I buy all of my initiators (e-matches) directly from MJG Technologies.

My reading is the OP is not looking for the complete e-match. He only wants the little red tube, thst is used on the MJG units (and others ).

Correct. Just the red cap. I tried McMaster Carr - no luck. I'm thinking there is some type of Plastic manufacturer making these things.

When I get home I'll attach a picture on how they will be used, but essentially these line the wall of the ejection well. I'll be using a high voltage arc e-match in place of the standard Pyro e-match.

Sleeve caps for Tube Ends looks like a really good start. I get the calipers out and measure the caps that I have and see if I can find a match. Thank you.

Here is the BP charge well photo
It is show with standard e-matchs. I will be trying these electronic e-match

But I need the little plastic cap to insulate the arc from the walls of the well and help contain the BP reaction

Did the OP find what he was looking for? I work with pyro so if he needs some I can put some in the mail.

 

[Tractionengines]

Do you know the OEM and Original PN for them....? As shown in your photo.

They came off e-matches manufactured by 3M corp. Sometimes we have to remove them (not the best idea) when fusing cakes for different types of effects. The ones in the picture came from some that are being prepared for disposal.

I’ve used and reused these red igniter shrouds in spent DMS motors to simulate motor ejection for ground testing parachute ejection.

The red shrouds are quite durable and can be reused several times.

Thanks everyone for your support. Getting some in the mail.
