It features a brass body with neoprene O-rings and 1\/4 in NPT end connections configured inline (inline male\/female options are typical in this family). The valve offers precise cracking pressure with zero leakage up to a high percentage of the set point and a positive reseat, with tamper‑proof adjustment to prevent drift. As part of Circle Seal Controls’ relief‑valve lineup (the 500\/5100 series), it is offered with PED certification and CE marking on most models, and the family includes options for vent‑to‑atmosphere or inline configurations across sizes from 1\/8 in to 1-1\/4 in. \u003c\/p\u003e\u003c\/div\u003e","brand":"Circle","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51678089117998,"sku":null,"price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_73261b73-61d4-4416-8863-44f489fc7580.jpg?v=1769571583","url":"https:\/\/plgautomation.com\/products\/circle-seal-controls-5133b-2mp-500-inline-pressure-relief-valve","provider":"PLG Automation ","version":"1.0","type":"link"}
