The Secure Seal Tester tests the thread integrity and proper seal of glass or plastic beverage bottles. With the proper attachments, the Secure Seal Tester can test bottles with aluminum roll-on closures, plastic closures, or steel twist crowns. May be used on bottles between 6 oz and 3 Liter capacity. Detects gas leakage rather than liquid for more sensitive, accurate readings. Rugged construction withstands production line abuse, yet is accurate for laboratory testing. Operates at 175(psi) minimum compressed air, nitrogen or CO2, but is capable of handling up to 3000(psi) inlet pressure. For glass bottles, must order appropriate puncture tip assembly. For plastic bottles, must order the correct size pressure fixture and cutoff tool.
