Bayonet Springs

Our range of springs are made to suit our range of caps. Springs are open coil and have a bell style end. Our springs are stainless steel and have a secure fit with our caps. If you require more information about our springs such as ID or wire thickness please contact our sales office.

Bayonet Adaptors

Our range of bayonet adaptors are made to suit our bayonet caps above. The pegs on our adaptors are tightly pressed in or, on newer batches, may be machined into the adaptor itself for extra strength. To match our adapters to our caps, ensure the number of slots is equal or more than the number of pegs. The caps ID is usually 0.5mm bigger than the adapter diameter for ease of assembly.
