Like most of our displays, the Model 337 is also available in a variety of other materials upon request. <\/p>\n<p>The seal is achieved using flat gaskets tailored to your requirements. We supply C-4400 fibre, PTFE, NBR and graphite gaskets, amongst others, as standard. <\/p>\n<p>For dark liquids or unlit tanks, the use of a reflective sight glass in accordance with DIN 7081 or similar is recommended. Due to the refraction of light in the built-in prisms, the liquid level can be more easily identified. However, if the tank is lit or if the colour of the product is visible, a transparent sight glass should be used. Reflective glass must not be covered with mica discs, as this prevents reflection.   <\/p>\n<div class=\"tabs-wrapper content-tabs\">\n<div class=\"tab-content\">\n<div id=\"item-description\" class=\"tab-pane fade in active\">\n<p>&nbsp;<\/p>\n<section style=\"max-width: 1000px; margin: 0 auto;\">\n<h4>TECHNICAL SPECIFICATIONS &#8211; Longitudinal sight glass type 337<\/h4>\n<table style=\"width: 100%; border-collapse: collapse; font-family: sans-serif;\">\n<tbody>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #ccc;\"><strong>Flange Material:<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ccc;\">Base Flange: 1.4571 (standard)<br \/>\nCover Flange: 1.4571 (standard)<br \/>\nOther materials on request<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #ccc;\"><strong>Shape:<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ccc;\">Longitudinal oval<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #ccc;\"><strong>Gaskets:<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ccc;\">KlingerSil\u00ae C4400<br \/>\nPTFE, FKM, NBR, Silicone, EPDM<br \/>\nGraphite<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #ccc;\"><strong>Total length:<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ccc;\">176 to 536 mm<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #ccc;\"><strong>Temperature \/ Glass:<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ccc;\">Up to 243\u00b0C with borosilicate glass complying with or similar to DIN 7081 (with saturated steam or hot water pressure)<br \/>\nUp to 280\u00b0C with borosilicate glass complying with or similar to DIN 7081 (without pressure)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #ccc;\"><strong>Optionals:<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ccc;\">Mica protection<br \/>\nSpecial designs available on request<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><!-- V\u00eddeo incorporado --><\/p>\n<div style=\"margin: 30px auto; max-width: 800px;\"><iframe src=\"https:\/\/www.youtube.com\/embed\/hQ8enKQjY_A\" width=\"100%\" height=\"450\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/div>\n<div style=\"text-align: center;\"><a href=\"https:\/\/aci24.com\/en\/products\/tank-sight-glass\/product\/59-longitudinal-sight-glass-fitting-type-337-pn-25\" rel=\"noopener\" target=\"_blank\">Website ACI \u2013 Longitudinal sight glass type 337<\/a><\/div>\n<p><a style=\"position: absolute; left: -9999px;\" href=\"https:\/\/www.pecta.pt\/en\/category\/aci\/\">ACI<\/a><\/p>\n<\/section>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The 337 oval sight glass is ideal for monitoring levels in closed vessels.
