A line of high-pressure, high-temperature pushbutton-switch sealing boots handle external pressures to 1,500 psi (103 bar), and temperatures from –80 to 400°F (–62 to +204°C). An armor-plated 300 Series stainless-steel external actuator mechanism protects an internal elastomeric sealing membrane. The boots come in two versions: p/n 1238/1SS with a 0.750-in.-diameter head and p/n 1238/5 with an oversize 1.250-in.-diameter head, and p/n N-1030T toggle-style silicone-rubber boot covered with a bonded nickel-plated brass cap.
