Usoro JPE na-agbanye na nickel plated brass T-ụdị tee bụ nkwonkwo eji ejikọta eriri ikuku. Ihe ya bụ ọla kọpa nickel, nke nwere ezigbo nguzogide corrosion. Ụdị nkwonkwo a na-anabata ihe nha nhata tee imewe, nke nwere ike jikọọ ikuku ikuku atọ na otu dayameta, na-enweta njikọ alaka nke usoro pneumatic.
Na sistemu pneumatic, ikuku PU ọkpọkọ bụ ihe a na-ejikarị na-ebufe ya na ezigbo nguzogide na iyi nguzogide, nke nwere ike ibunye gas nke ọma. Usoro JPE na-agbanye na nickel plated brass T-njikọ nwere ike iji ya na ọkpọkọ PU iji nweta njikọ nke usoro pneumatic.
Nhazi nke nkwonkwo a na-eme ka njikọ ahụ dịkwuo nchebe na ntụkwasị obi, na-egbochi nkwụsị gas nke ọma. N'otu oge ahụ, nickel plated brass material nwekwara ike inye ezigbo conductivity, na-eme ka arụ ọrụ nkịtị nke usoro pneumatic.
