Brand: SPA Design Racing Products
This is a replacement for the push-in fitting used on SPA mechanical firing heads. The 1/4 NPT male threads fit the SPA firing head (mechanical only). The other end accepts 6mm (1/4") Dekabon Tubing (Part No. 2456-.250). It will not work properly with bare aluminum tubing. Sold individually.
SPA Electrical firing heads use the smaller SPA 1/8 to 6mm (1/4") Push-In Fitting (Part No. 2458).
