SharkBite-type push-to-connect fittings: tube insertion depth by size, 1/4 to 2 in (copper, PEX, CPVC) — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/sharkbite-push-to-connect-insertion-depth/ (sheet CC BY 4.0) Basis: SharkBite's installation guide (insertion depth in inches and mm), with the values printed in SharkBite's SBDC35 catalogue, an Aqua Dynamic manual and a third-party how-to shown beside it where they differ; numbers only Catalog version: 2026-10-20 Sizes: see table below - Insertion depth is how far the cut, deburred tube must be pushed into the fitting to seat; the guide says mark the tube at that depth and check the mark meets the fitting face. Rows are SharkBite's installation guide in full (fitting size = nominal CTS size, pipe OD = nominal + 1/8 in, depth in inches and the mm printed beside it). The guide lists these pipe types as approved: PEX (ASTM F876, CSA B137.5), copper (ASTM B88), CPVC (ASTM D2846, CSA B137.6), PE-RT (ASTM F2769) and HDPE (SDR-9, ASTM D2737). - The sources disagree, so the other values are shown beside the guide's, not averaged. For 1/2 in: guide 0.95 in, Aqua Dynamic manual and the third-party article 1 in. For 3/4 in: guide 1.10 in, both others 1-1/8 in (1.125 in). For 1 in: guide 1.31 in, Aqua Dynamic 1-1/4 in, the third-party article 1-1/2 in. For 1-1/4, 1-1/2 and 2 in the SharkBite SBDC35 catalogue prints 2, 2-1/4 and 2-1/2 in against the guide's 1.88, 2.05 and 2.19 in; the catalogue text read gives these under the installation and slip-feature wording and does not say whether they are insertion depths for the same product, so check the guide for your fitting. Use the depth printed on or with the fitting you are installing; a 1/8 in difference between sources is within what a marked tube shows. - The Aqua Dynamic manual is for a different maker's push-fit fitting, shown because it prints a comparable table; the other makers' depths are not SharkBite's. - Not published as numbers in anything read: fitting body diameter and length, the stainless grab ring and O-ring geometry, tube stiffener dimensions. No file is drawn (nothing defines a body). McMaster-Carr sells SharkBite-compatible push-to-connect fittings with per-part STEP; its category pages and SharkBite tool page are linked, not copied.
